Mangopassion: I think I share the concern. Although my DD8 is not very bothered by these colors, I want to find out a bit more about how she process all the infomation; and to benefit for homeschooling as well.
She has always had it, and doesn't complain. She says she plays with those colors sometimes. I found a book "Mango Shaped Space" at our library. I was going to read it, but my DD seems to be enjoing the book. I am waiting for another book "When Frog Croaked Blue" to be delivered.
At this time, I'm trying to figure out how much does my DS6 sees colors. It sounds like he sees only with music.
