Color Tips (from a non-designer): "1. Maintain the color intensity. If you go for primaries, don't wimp out. Try it. 2. Designate one room as an experimental space (In my case, the "test kitchen"). I think you have more color leeway in kitchens and bathrooms, especially since you can readily find color accessories for these rooms. 3. I can't say enough about colorful fabric. When I find something I like, I buy it and find a use for it i.e. pillow cases, stretched across artist frames for a wall hanging. Instant color and texture, and if you don't like it, you can get rid of it fast."
Color Resources: "2 budget-conscious color resources: 1. eBay is an awesome resource for accessories and gadgets. Pick a category and search by color. A purple cake stand? A bright red juicer? Yes, please! I snatched up more than enough Marimekko fabric (two patterns, many colors) to cover the kitchen for about $50. 2. Check out the "oops" paint shelf at Home Depot if you want to refinish a single piece of furniture or paint a piece of canvas for a floor or wall covering. And if the color doesn't work out, you only spent a couple bucks."
