I'm about to paint my son's room blue and went through about 15 samples. I ended up painting those samples on 8x10 card stock ( I like the stiffness of the paper) and taped them to his wall and pondered them for days in different light. His curtains are brown and bedding is a lighter taupe brown so I'm going for the chocolate brown/blue scheme. I ended up going with a Martha Stewart color but mixed in Behr paint (without the primer). The color is "Twilight". In fact I had a mixture of MSL, Benj Moore & Valspar chips sampled in Behr paint. I like Behr because of low odor and it rolls on good for me with great results.

I'm familiar with Dolphin Fin color but recently painted my pantry Benj Moore "Coventry Gray" but in the Behr paint (with the primer)turned out lovely! I think I'm going with that in the kitchen also. Looks great with white which is what I may be painting my early 90's builder oak kitchen cabs!

Good luck and have fun!
