Frugal and Energy Efficient Living

Always use high quality paint, preferably latex, inside and out. Less paint, fewer coats, longer lasting. Odd colors are fine for the things you mention or maybe one wall. I was a painting contractor for a few years when my daughter was a toddler. I gave her a wall in my apartment and all the left over paint from jobs I was working on. That wall was amazing. A constant work in progress.
