I’ve never thought of myself as a “blue” kinda gal, but I’ve always loved aquas. And of course, the notion of complementary colors - blue/orange being more favorable in real life organic settings than red/green and yellow/purple.

I’m drawn to these mod combos, perhaps because they’re mod shapes to begin with. However my victorian mansion doesn’t really go with boldly contrasting colors….

and at the same time… you dont necessarily have to match your colors with your venue… if only you saw the colors of my venue carpet… ouch!
