>>5946435Also personally for me in traditional I still use the traditional Red, Orange, Yellow, Green, Blue, Purple system for thinking about color mixing where Red-Green, Blue-Orange, Yellow-Purple are complementary, even though they are not technically complementary, just close enough for the impreciseness of pigment based mediums.
It's not an exact science and ignores the larger color gamut potential of cyan and magenta pigments.
But the idea is just to be able to label any color you see as belonging to a family of hues so you can push it closer or further away from that color to the color you want by thinking about this very simplified color wheel and rough complementaries.
If you want scientific complementary colors, representation of cyan and magenta and better spacing you just use an RGB color wheel like photoshop that is based on light but you don't use it to color mix like traditional, you just use it to plan your color schemes, complementaries and for gamut masks.
If you look at color afterimages (look at a screen of blue for 30 seconds and then look at a white surface) you will see RGB complementary colors.
