I dunno how orange looks to me. I can see orange, but whether it looks to me the same as it looks to you is highly debatable.
Chartreuse? I don't have a clue what that's supposed to look like. If it's what I think it is, it looks either gray or muddy brown.
One of the first major emotional traumas in my life was when I used purple to color the ocean when I was in kindergarten and I got teased for it. I didn't know it was purple -- I couldn't see the red in it, to me it looked like navy blue.
I'm colorblind also. Pink would be a terrible idea, for the same reasons.
On the how we see color: For my birthday last year, my in-laws bought me some colorblind glasses.
They claim to filter certain wavelengths to let you see color normally.
I can't speak to if it really works, but it lets me see colors differently. For example, I have a purple shirt and a blue shirt that look almost identical to me, just barely a different shade.
Put the glasses on and the difference couldn't be clearer. Other colors become MUCH more vibrant.
Pinks, even ones I could see before seem fluorescent to me. Blood red becomes a bright color instead of a deep color. Sky blue ( as in the actual sky) becomes.... Uhh... More blue?
Construction/hunter orange ( here's where it applies) goes from pleasant, deep orange (as I usually see it) to an obnoxious orange, which is likely more what it appears to normal people.
Effectively, most colors are subdued to me without the glasses. Gives me an idea of how people have strong feelings about color choices. (Mostly I don't care.)
Yellow seems the only color unaffected by the glasses. Whether that means i see it correctly or the glasses just don't change it, I can't say.
