Colour-blind-what they see

Your mom didn't know until the 80's? Knowing your approximate age, that is a long time to not have figured it out. LOL.

I'm sure he'd told her that he was color-blind, but I don't think she really knew that it meant that red and green were the same color for him. I guess it took the shock of a pair of lime green jeans for it to really sink in!

I have a hard time with those intermediate blue and green shades. I often think blue is green, and vice versa. I also frequently think grey is blue. Sometimes I think black is dark blue. I am not sure if I am colorblind or just color-challenged. I think I see the color correctly, I just don't know what to call it. My friends enjoy making fun of me as a result. Regardless, it is a fashion nightmare.

The other extreme is tetrachromacy. i heard about it years ago so I had to look it up. And yes its in Wiki. interesting. And no it does not allow you to see in ultra-violet nor in infra-red region. Just more variation in color like we just don't have enough.

When I was growing up, I knew a boy who was partially color blind. It seems like you can have partial color blindness. It's not all or nothing. If one of the primary color cone is weak, your ability to distinguish between red and green is reduced. I don't remember what the boy told me about color red and green... I think he said it was muted and looked very much alike.

I have a form of color blindness. I can't see shades. Light blue, light green, light yellow all look white to me. My car apparently has some dark blue in it but all I see is a deep forest green. What is weird is my brother, we share the same mom, sees colors just fine.

Very interesting these other forms of colour blindness or whatever. I had no idea.

Wonder how it affects artistic renderings for anyone with colour blindness and doing art involving colour.
