EPILEPSY WARNING, this uses rapidly switching costumes to generate impossible colors. Also, use turbomode By rapidly flashing colors, it is possible to fit more than 3 channels into one spot, creating impossible colors. Unlike using stereoscopic impossible colors, which can be hard to view, require two healthy eyes, and can only go up to six color channels, rapidly flashing colors (also known as time colors) are able to fit as many colors as your display can flash, though 6 channels is already more than enougth, and they do keep a flashing look. This project has 4 examples, which you can cycle through by clicking. Example 1 (default): Reddish-green and greenish-red. By themselves, they would be indistinguishable, but next t9 each other, they are different. Weird. Example 2: An approximation of a tetachromatic hue sphere, projected to an unfolded tetrahedron. The reason white is at the middle is because it’s (technically) desaturated: it has R, G, and B, but none of the 3rd channel. Example 3: More impossible colors. This is not every color that can be created with two images: that would need a 6 dimensional cube, as if displaying the whole RGB cube wasn’t hard enougth. Example 4: An interesting one. Instead of using the second image to fit a 4th channel to simulate a new cone, we fit a 3rd channel to simulate a common cone (here blue). This could have applications with colorblindness. This is also the analog of dimensional analogy for color: we can think about extending trichromatic colors to tetrachromatic colors by thinking about extending dichromatic colors to trichromatic.
