Custom Color Vision V1.21 

OS: Windows 11 64-bit. With Windows 10 (version 1809 or later) the overlay functionality doesn't work: you have to uncheck the isOverlay toggle and can only use the pop-up overlay (with 2 physical/virtual screens). 

Processor: Intel Core i5-2400 @ 2.5 GHz or AMD FX-6300 (4 hardware threads)

Memory: 8 GB RAM

Graphics: DirectX 11–compatible GPU with ≥2 GB VRAM (GeForce GTX 660, Radeon HD 7870, or newer integrated Intel UHD 630)

DirectX: Version 11 (feature level 11_0) 

Storage: 500 MB available space

Display: 1× monitor up to 1920 × 1080 at 60 Hz 

Delivers roughly 20–60 FPS at 1080p with one overlay active and no other applications running concurrently.

OS: Windows 11 64-bit (23H2); Window 11 is highly recommended because the overlay functionality only works on Windows 11!

Processor: Intel Core i7-8700 or AMD Ryzen 5 3600

Memory: 16 GB RAM

Graphics: NVIDIA GeForce GTX 1070 Ti / RTX 2060 or AMD Radeon RX 590 / 6600 (≥4 GB VRAM)

DirectX: Version 12 (feature level 12_0 – fully backward compatible)

Storage: 1 GB available space

Display: Up to 2560 × 1440 @ 75 Hz, multiple-monitor 1080p setups (a higher native screen resolution will cost more performance)

Holds 40–60+ FPS at “Maximum (1080p)” with one overlay active and no other applications running concurrently.

1: logo and application name

2. minimize application

3: close appliaction (closes all related windows)

4: drag & drop in custom texture (1D spectrum, 2D image), hover to see file name of dropped in image; when an image is dropped in there appears a line that you can drag up and down to select the specific horizontal hue line, there's a limit of 32 horizontal segments (i.e. 32 spectra in one image, minimum vertical size per spectrum is 4 pixels)

5: segment display (shows which segment of the dropped in image has been selected)

6: auto-scroll speed display, from 0 (none/inactive) to 100 (very fast auto-scrolling)

7: auto-scroll speed slider (adjust left to right to change auto-scroll speed); you can't adjust the vertical color texture selection in the main window while the auto-scroll speed is above 0; does not work while remote controlled segment value support is active

8: start/stop button (starts or stops the application's (pop-up) overlay and color conversion

9: screen selection dropdown (lists all the active screens)

10: quality selection dropdown, 1080p (slowest but high quality) to 360p (fastest but low quality)

11: screenshot button (can only be pressed while the application is running)

12: main information display (shows loading, running, overlay, simulation and line state)

13: overlay FPS display (shows the current FPS, updates every second)

14: FPS limit (1-240, the value represents the frames per second)

15: FPS limit toggle (if set to false it's limited to the native FPS)

16: overlay toggle (true = overlay; false = pop-up window)

17: opens the info pop-up window

18: maximize/minimize window

19: spectrum shift percentage display

20: spectrum (horizontal) shift slider, horizontally shifts the custom texture

21: vertically expandable custom texture area to enlarge detailed custom textures

22: first custom texture bar (whitish triangle arrows); this bar will appear when a custom texture has been dropped in or loaded; left mouse click/drag to move the bar up and down and select a specific horizontal segment of custom texture; can't be adjusted while either auto-scroll speed is above 0 or remoted controlled segment value support is active

23: second custom texture bar (bluish triangle arrows); this bar will appear when a custom texture has been dropped in or loaded and if the interlaced colors support toggle is active; right mouse click/drag to move the bar up and down and select a specific horizontal segment of custom texture; more info in "How to Use (Controls) → info pop-up → 17"

1: logo and application name

2. close appliaction (only closes this window)

3: application information (app name, studio, developer/copyright, version, website, etc.)

4: screenshot directory display/input field

5: screenshot directory button/browser (opens the native Windows file browser, select a valid directory, automatic saving if valid)

6: "ok" button (closes this pop-up window)

7: custom key binding for start/stop button (of the main window)

8: custom key binding of the screenshot button (of the main window)

9: full display resolution support toggle (fewer FPS if activated and selected in the main window's quality selection dropdown); when activated a new option shows up with the current selectable maxiumum resolution; determined by your Windows and monitor settings

10: hue band resolution slider; the higher the number, the more distinct hues; the lower the number, the fewer distinct hues

11: custom amount of vertical segments (0-∞); this feature is useful for bigger and more detailed custom textures and for the remote controlled segment value support

12: maximum auto-scroll speed (seg/s = segments per second); for example, a value of "10" will cause the active auto-scroll speed to move 10 segments per second; the higher the number, the faster the auto-scroll speed

13: save custom spectrum image toggle; automatically saves the custom texture (custom spectrum image) across sessions if activated

14: remote controlled segment value support toggle; the segment value of the main window will adjust according to the single integer value of the linked text file (if the text files has been saved); you can't adjust the custom texture bar in the main window while this toggle is active

15: directory display/input field of the text file for the remote controlled segment value; text file should only have one integer value (0-∞); text file needs to be saved after every adjustment for Custom Color Vision V1.21 to register the value change

16: directory button/browser of the text file for the remote controlled segment value (opens the native Windows file browser, select a valid directory, automatic saving if valid)

17: interlaced colors support toggle (slightly fewer FPS if activated, the percentage of fewer FPS also depends on the complexity of the inserted texture map); activates interlaced colors; introduces a second custom texture bar (bluish triangle arrows) that can be adjusted with right click/drag

18: texture map drop-in area; preferred aspect ratio 16:9; preferred dimensions equal your selected quality settings, but 1920x1080 is preferred (even for worse quality settings); [white to gray] equals the first custom texture bar's selection; [black to gray] equals the second custom texture bar's selection; preferred colors for the texture map are pure black & white; texture map only updates when dropped in if interlaced colors support toggle is active

1: logo and application name

2. minimize application (cannot be recorded if minimized)

3: maximize window

4: close overlay pop-up window (IMPORTANT: Don't close this window! Rather stop the application and set isOverlay to true to disable this window. Bugs can occur if the overlay pop-up window is closed in any other way.)

5: screen capture display with color conversion applied

6: right click on window: opens context menu for selecting the scale of the window (aspect ratio: 16:9)

1: inserted custom texture (image)

2: make sure that the vertical segment in the info pop-up window matches the vertical pixel amount of the custom texture (image); if both values do not match, then the automatically set segment values in the main window might not directly match the linked text file's custom segment value

3: input a single integer value into the linked text file, save the text file (important), and if the remote controlled segment value support is active, then the main window's segment value and custom texture bar will automatically adjust to match the text file's custom value

4: activate the remote controlled segment value support toggle to active this feature; while this toggle is active you cannot directly adjust the custom color texture bar by hand

5: either use the windows file browser via the respective button to select a text file or insert the text file's path by hand into the input field; make sure the text file is readable/writable and that the directory/path is correct and accessible; the text file should contain only a single integer value and has to be saved for the changes to be registered by Custom Color Vision V1.21 

(not hierarchically listed)

• On some PCs the custom taskbar icon might not be set/visible. (25.07.2025, Version 1.21)

• FPS will waver/decrease while other CPU-intensive applications are running, depending on how good your PC setup is and depending on how many pixels are actively changing (e.g. still image = less FPS; for saving resources). (25.07.2025, Version 1.21)

• If you're running the overlay pop-up on a second screen and recording the first screen, but the first screen has no pixel changes, then temporal colors will not work. Currently, there have to be pixel changes for the temporal colors to work in this specific case. (25.07.2025, Version 1.21)

• The mouse cursor isn't visible in the overlay pop-up display. (25.07.2025, Version 1.21)

No, currently not. Other OS support isn't planned yet.

It's because of a weird Windows 10 quirk. Sadly, it currently seems impossible to make the overlay functionality work for Windows 10. I've tried a lot to make it work, but it seems to be a persistent and currently unsolvable bug. Essentially, when excluding a window from capture, instead of capturing the pixels behind that window like in Windows 11, Windows 10 returns black for the same area. This makes it impossible to create the overlay functionality on Windows 10 using reasonable strategies.

Yes, you can drop in just a 1D or a 2D texture/image. In the latter case, you can choose which horizontal line of the 2D texture will be taken as the current custom spectrum. Drag the selection line up and down to select a specific horizontal segment.

See the minimum and recommended system requirements. Naturally, the better your setup, the higher the FPS. Select a lower quality in the quality dropdown list for better FPS—it's a tradeoff. Any resolution above 4k (accessible by activating "full display resolution support" in the info pop-up window) will naturally result in fewer FPS because exponentially more pixels are being adjusted.

If the screen is relatively still and not a lot of pixels change, then the FPS might decrease until enough pixels change again in order to save resources. This will cause the FPS to fluctuate naturally.

Yes (with Windows 11). You can run the app with any number of active screens, including just a single screen. However, in order to select more than one screen you have to open a new instances of Custom Color Vision V1.21 and run them concurrently.

Yes, the loaded texture that you've dropped in before closing the app can be saved when the "save custom spectrum image" toggle is activated. All interactive elements of the info pop-up window are automatically saved.

No, you can't record the overlay because it's excluded from capture. However, you can take screenshots of it. Alternatively, you can record the pop-up overlay when the isOverlay toggle is set to false. To optimally record the overlay pop-up you need at least two phyiscal or virtual screens and a PC setup that can handle both recording and color conversion without causing lags or FPS drops.

No, the app won't cause any performance issues while being stopped. It will be on standby, with minimal resource usage.

Don't worry. Just close and restart the app. If the issue perists, please visit the Ooqui Sensory Lab Discord server so that I can help you troubleshoot any issues.

Yes. As long as you don't have a "potato PC" you can also use this app on a relatively low-end PC setup, as long as it's Windows 11 (without "overlay functionality" also Windows 10). Select a lower quality in the quality dropdown list for better FPS—it's a tradeoff.

The overlay of Custom Color Vision V1.21 doesn't work for some exclusive fullscreen windows. In this case, try to use different window settings (e.g. borderless fullscreen, borderless window, windowed).

Version 1.20 is the first official and publicly released version of Custom Color Vision. The version system that I use is a way for me to keep track of the many development instances of Custom Color Vision that I have already made.

Yes. Almost any aspect ratio is suitable.

Yes. Generally, the lower your native screen resoltions, the higher the FPS will be. The higher your native resolution, the lower the FPS will be. FPS also depend on your specific PC setup. You can activate "full resolution support" in the info pop-up window.
