Color images are defined by red, green, blue (RGB) values at each pixel. What if instead I wanted to define pixel colors by orange, black, and yellow? Is there a way to change the basis of colors from RBG to OKY (orange, black, yellow) in order to define my pixels in terms of these new colors?
Orange, Black, and Yellow technically "Span" the same "colorspace" as Red, blue, and green, so I should be able to recreate colored images with these 3 colors right? How could I calculate the conversions from RGB to OKY.
I have a image that is predominately composed of black, orange, and yellow colors. Therefore black, orange, and yellow is a more natural "color basis" for this picture than Red Blue and Green.
So how would I figure out the conversions?
