That'd be HSL-ish, sort of like NES except including more desaturated midtones. It'd be simple to implement a composite output circuit for (assuming an 8*CB crystal), but I can't so easily show the parrot for this one because it has 8*8*8-8*7 = 456 colors, and GIMP won't quantize to palettes with more than 256 colors.zzo38 wrote:I thought of a different kind of colorspace: 3-bits high-voltage, 3-bits low-voltage, 3-bits phase. The phase only covers half, because you can get the rest of the phases by inverting it which is done by switching the voltage. If high-voltage and low-voltage is same then the picture will be gray.
Sik's suggestion to subtract the intensity instead of adding it would be mathematically equivalent to the purely additive RGBI if defined as follows:
Red: #300, #700, #B00, #F00
Green (add): #030, #070, #0B0, #0F0
Blue (add): #003, #007, #00B, #00F
Intensity (subtract): #333, #222, #111, #000
