Paintings painted in 6 dimensions of dichoptic color and 4-dimensions of dichoptic hue are waiting for you!

System Requirements & Virtual Reality (VR) Suggestions

OS Compatibility: Windows 10 & Windows 11.

Hardware: The application is designed to run efficiently on most standard modern hardware configurations, meaning high-end specifications are not required for satisfactory performance. However, good performance of the application ultimately depends on your personal setup and cannot be guaranteed, especially regarding the VR mode. In general, the lastest Windows 11 version (last update 07.01.2026) is highly recommended and has the highest compatibility.

Virtual Reality requirements/suggestions:

a VR headset with a trichromatic display for the optional VR mode
a PC that performs well when actively using VR (including standard keyboard and mouse)

You don't need the VR headset's controllers while running the application, only for setting it up. This is a PC-VR application (i.e. both PC and VR are necessary for the VR mode) that seeks to be compatible with as many VR headsets as possible, meaning that in-game controls are executed via keyboard and mouse actions. Important: This application cannot be played in VR without using both a PC and a VR headset. For the stereo viewing modes a standard PC setup is sufficient.

This application was already tested on the Pico 4 VR headset, using Pico Connect for the necessary PC connection and SteamVR for running this game in Virtual Reality (i.e. a Virtual Reality platform/engine that serves as a universal hub for VR games and apps). Other modern VR headsets and setups are likely but not guaranteed to work.

Programmed on:

OS Name: Microsoft Windows 11 Home
Version: 10.0.26100 Build 26100

How to Use (Controls) & Functionalities

Hexachromatic Gallery (main application)

The following slideshow of images explains most of the controls, functionalities and shortcuts for Color in Color: Hexachromatic Gallery. You can also find these explanation images in the gallery space inside the game before a custom gallery has been loaded.

Additional functionalities

Stereo Image & Gallery Setup: Press F on your keyboard to open Window's file browser and select a suitable art gallery folder. If the art gallery folder and the stereo images it contains are correctly setup, this is all you have to do to load an art gallery folder.

Custom Gallery Art Naming: The following image shows an art display. Every art display in the gallery is automatically named using the corresponding image file name. The logic is as follows: "title_artist_description" (without the quotation marks). Here, "_" is used to separate each file name into 3 different text areas on the art display, the mid part (title), the top part (artist) and the bottom part (description). The topmost text area displays the folder name (i.e. the gallery name) in gray.

If you want to name art with only title, artist and/or description, simply use the following logic:

"title_artist_description"
"title_artist"
"title__description"
"_artist_description"
"title"
"_artist"
"__description"

Custom Gallery Audio: The first found audio file in the loaded gallery folder will be played by the loudspeakers that you can find inside the gallery space. Adding "loop_" (case-sensitive) in front of the name of the audio file will make it indefinitely loop. Without this prefix the audio file will stop playing after its playback time has concluded.

View Modes: The following 3 images show the 3 view modes, switchable by pressing TAB on your keyboard.

Monocular

The monocular view mode is the most accessible, but cannot show dichoptic colors. Press R on your keyboard to switch the eyes' perspectives to get a better understanding of the dichoptic art.

Binocular/Dichoptic (Horizontal)

The binocular (or dichoptic) view mode is perfect for viewing dichoptic art through stereo viewing techniques, like cross- or parallel-eye viewing.

Important: Make sure to ease into using cross- or parallel-eye viewing techniques! If you're a beginner and you're overusing such skill-based techniques, you might temporarily get excessive eye strain! Implement frequent pauses based on your skill level!

Press the O key to switch between flat stereo, cross-eye stereo and parallel-eye stereo.

VR Video Recording (Vertical)

This mode is intended for recording VR videos in a stereoscopic 3D (top/bottom) layout, which yields the highest possible quality.

Important: Further editing of the video footage is needed, since this is raw data. E.g., for YouTube VR 360° videos, you want to make both perspectives proportionally smaller so that they don't span the whole 3D screen environment.

Press the O key to switch between flat stereo, cross-eye stereo and parallel-eye stereo.

Easy Screenshots: Press the G key on your keyboard to save a screenshot to the "6DGallery_Screenshots" folder on your desktop. If there's no folder with this specific name yet, it will create a new folder with that name.

Stereo (3D) Depth Toggle: Press the O key on your keyboard to toggle the depth effect for the two stereo view modes (i.e. not for the VR mode).

Depth Cycle:

No Depth
Stereo Cross-Eye Depth (default mode)
Stereo Parallel-Eye Depth (inverse of cross-eye depth)

With 3D Depth Effect (Cross-Eye)

Without 3D Depth Effect

Art Galleries

You can find free and paid art galleries on the itch.io page of Color in Color: Hexachromatic Gallery. New art galleries may be added in the future. Of course, you can also create your own art galleries, e.g. with Color in Color: Hexachromatic Paint.

The following screenshot shows how an art gallery folder approximately looks like.

Important: Make sure that your art gallery folders aren't nested too deep into other folder structures. If the folder and file paths are too long, images might not load correctly.

FAQ (Frequently Asked Questions)

Is this application Windows only?

Yes, currently Color in Color: Hexachromatic Gallery is only available for Windows 10 and Windows 11.

Where can I get support/help if I have any problems with or questions about the application?

First, please read this website for the Color in Color: Hexachromatic Galllery very carefully once again. Your question might have already been answered resp. your problem already solved, and you might have just overlooked it.

If there's still questions and your problem hasn't been addressed, you can get help and support on the Ooqui Sensory Lab Discord server.

I might or might not reply! Support is currently free, so it's entirely dependent on my time schedule, and whether I can or want to help with solving your problems and answering your questions! Only use the support e-mail if your feel like it's absolutely necessary!

Why are most objects in the game gray?

I've chosen whites, grays and blacks as the predominant colors to combat cone fatigue and afterimages, as well as to provide the most neutral color context possible.

Do I need a VR headset to play this game?

Color in Color: Hexachromatic Gallery is designed for both PC and PC-VR. You can play the game in stereo (via pressing TAB) by using cross-/parellel-eye viewing techniques or in VR with the necessary setup. If you can't use stereo viewing techniques and don't have a VR headset, you can get an idea of the dichoptic art by pressing R on your keyboard to switch the eyes' perspectives.

Can I view stereo 3D images with this game?

Yes, you can! This game perfectly works for viewing stereo 3D images as well (i.e. not Anaglyph 3D). Use the R key on your keyboard to switch the eyes' perspectives if the stereo 3D images are oriented the wrong way (needs to be done manually for every new floor).

Can I play this game if I'm color blind or color vision deficient?

Yes, you can! Although you won't see as many new dichoptic colors as normal trichromats, you will still see a lot of new dichoptic colors of your dichromatic or anomalous trichromatic colors. Later on, there may be art galleries that are specifically designed for dichromats.
