Benjamin Moore makes a very nice low VOC paint. It covers well, cleans up easily and leaves no odor - none at all. I did some painting in the late afternoon and when DH came home a few hours later, he didn't believe I had painted because there was no telltale smell.
Even more impressive - we have a pet that reacts to "everything" (he could be the quality control inspector for any green product company!) and he was just fine during and after the painting. That may not mean anything to you - but, if you knew our pet's history, you would be impressed.
DH and I would never use a regular paint indoors again, having seen for ourselves that we didn't have to compromise on quality to use a safer product ... even if we didn't have our pet insisting we go "green"!
