I missed the post about the quilt, but colour issues . . . . Well, that's not just a male thing although statistically (obviously we have brilliant exceptions John!!) women have MUCH better colour differentiation than men.
Years ago my sis asked me to make a quilt for the bedroom in her new house. She kept forgetting to show me the carpet/paint/curtain samples, so finally when we were out shopping I took her to a store and told her to pick one fabric and I would puts others with it. She chose a really nice med/dk olive shade of green with a small print. I then collected about 60 other greens (lime to dk olive) to make her a scrappy quilt.
Just as I had started it she remembered to bring the amples - pale blue/green spearmint colour!! She just looked at me and said "Yeah, they're both green".
It was only then I realised that sis was more than a little colour blind. She always dressed VERY smartly, but thinking back it was always white/off-white/very pale shirts with plain very dark suits at work. And leisure wear back then was even more "anything goes" than now colour-wise. So I guess we just never had any reason to notice. Her first house was entirely black, white and shades of grey - curtains, blinds, furniture, carpets, tiles . . . . . everything!! We just thought she was a bit "odd" but it turns out she really didn't notice anything unusual about it. lol She probably still doesn't think she is colour challenged!!
