To be fair how colors mix with light vs paints are completely different. With light, maroon is made by combining mostly red with a small amount of blue and reducing brightness—since additive mixing can’t produce true dark tones, it relies on dimming. With paint, maroon is created by mixing red with a bit of blue or black, which absorbs more light, naturally producing the dark, muted red. So in light, maroon is a dim, cool red; in paint, it’s a red with absorbed brightness and added depth.

computers use additive color, pigments use subtractive color.
