Being in a rented suite and on a perpetually tight budget, adding colour allowed us to create a warm, distinct feel for each room while retaining a sense of unity throughout the apartment through the limited palette of our furnishings.
2 Good color tips: 1. If in doubt, consider the materials of your furniture and choose contrasting colours that will bring out their beauty. I love wood against vibrant, cool shades that bring out its golden tones. 2. I also recommend bright, analogous colours that almost vibrate together, such as a red-orange with magenta. However, I find the darker and richer the tones, the less it seems to work -- as with navy and black, my least favourite pairing!
Favorite type and brand of paint: Benjamin Moore has served us well.
