My daughter in law buys the sample cans and paints good size swatches on the wall. She buys 2 in the family of color she thinks she wants and 2 or 3 of new ideas. I used samples the last time we hired painters and it was the best thing we did. YES my dark brown sewing/guest room has lots of natural lite and also Ott lite and 3 other lights if needed. Two people have copied my brown room - its OK since we don't entertain the same people :-) Just thought I would mention the samples and seeing swatches - I think it helps.
