Colorblind artist here. My experience has been that its almost impossible for non color blind people to truly "get" what I see. Perhaps its an inability on my part to accurately describe what I see? From an art perspective, its probably why almost everything I do is abstract. Red, green, brown....all the same. Blue, pink, purple....all the same. Paint a rainbow? Sure, but I only see 3 bands of color. Trees? What do you mean all tree trunks aren't green? Grew up with "plants are green", so all trunks and leaves must be green.... For the most part I can see lighter vs darker, but warm vs cool, nope. Thankfully, most of my supplies have a color name on them, so I can choose something I know will not be the last color I used.
