I use mostly cool tones and pastels closer to the house, and brighter, hotter colors further away where they show up from a distance. But some hot colors I find difficult to partner with other plants, like the scarlet Poppies and the Geum- seems like a lot of blooms just don't show up near those 55 mph colors. I think if I get them combined with bright yellow, purple, and white, I'll be a lot happier with them.
