My son is color blind and we have been having many interesting conversations about it similar to this. Your note about the program seeming to add in blue for instance, apparently according to my son its actually accurate! Upon investing we discovered that for those of us with tricolor vision blue is actually hidden in far more colors than you would know. When you strip away the red and green, or anything that has those, the blues and yellows that we couldn't see because they were overwhelmed by other hues start to take presidence. He once pointed to some wine red iridedcent flowers and said "WOW, Those dark blue flowers have such bright yellow stems! I love them!" And left me totally confused for a minute, he also ADORES sunflowers, because many yellow flowers (like the daffodils I tried to grow for him) have too much green tint, and end up looking muddy, but the sunflowers we grew had more pure yellow.
