I'm currently making a quilt for my GD for college. I had her pick the fabrics. She did a super job. I knew she was going to want yellow or orange and that would be a stretch for me. Not my favorite colors. She ended up with a focus fabric with yellow, two shades of blue, lime green on a white background. We are making a D9P and the center square is a bright yellow and that's the one that is cut in four small squares. It pops out in the overall design. The prints are a mod design (younger generation). She has seen some of the blocks and loves it. It's growing on me. I'll try to post pictures when I get it done - hopefully before college starts.
I have a neighbor that is color blind and the only colors he can see are yellow and green. Interesting.
My flower beds are mainly pinks, purples and whites. White to make the other colors pop. In the flower bed clear across the yard I have daffodils (spring) and now have planted big yellow marigolds so they can be seen from the distance.
God put yellow centers in most of the flowers. Must be a good color.
