The base unit of color photography is a 3-valued pixel. What color they transmit depends on their relative value and their order.
Tap the screen to explore these permutations. Find your best lighting, then snap a photo or record a video.
Take a step further and project alternate (LAB, HSV) representations of light onto an RGB-representation.
Finally, long press the screen to invert each pixel's 0-255 value.
All photos/videos saved in a folder titled "Portal Gun" located in your Pictures directory.
