Commodore VIC-II Color Analysis (Preview)
The C=64 (with its VIC-II chip) features a palette of 16 colors.
Black, White and the three Greys are no colors and the "light"-versions of Red, Green and Blue are just brighter versions of Red, Green and Blue. That leaves us with eight unique colors.
Since the color-palette of the VIC-II has been made for the TV-system, we aren't talking a RGB-color-space, but a YUV-one (for PAL-TV that is), that we can convert to RGB later.
"Y" in the YUV-color-space is the Luma-signal which is just the "black&white-part" (the brightness) of the colors. "U" and "V" are color-difference signals, which together describe the hue and the saturation of the colors.
