It took me a long while to believe people didn't see colors the way I do. I seem to have a sensitive ability to see slight variations in hue, value, tone and tint, and it helps me enormously in quilting. I teach this in a special class I've developed and get responses from participants that it's the best color class they've ever attended, but I still see that they have trouble. After taking many of those online game/tests, sort of wish I'd been a pilot!
