I get color inspiration from lots of places. Sometimes it’s deliberate for a mood. Sometimes it’s what’s available in stash. Usually I like value contrast. And mix the temps; warm/yellow &orange with spot of cool/periwinkle. This particular one is split complementary.

Color for a mood....
 

Hmmmm....I like the way you stated that you sometimes use color for a mood when choosing your fabrics for a quilt.
I find certain colors make me happy. In our guild color wheel program, I leaned the term you used: spit complementary.
I tend to select the same temps in my quilts...all warm or all cool colors. Its time for me to Mix things up!

Thanks everyone for your tried and true tips on Color! Keep them coming!
