This post is already a few years old now, but it seems to be making the rounds again, and rightfully so.
Before Muddy Colors existed, artist Jonathan Linton posted an article on his blog detailing the results of his 'White Test' experiment. Jonathan sampled dozens of different brands of white oil paint, let them age for 5 years, and then rated them on much they yellowed over the years. The results may shock you!
I, for one, am changing my brand of white immediately.
