Title: Neutral grey wall paint.
Post by: felix5616 on December 15, 2014, 11:43:05 am: I have prevoiusly used Behr paint, a formula that was designed as neutral gray. The tints are no longer available due to mandated paint formula changes. Anyone have a new formula that they a using?

I'd just take a 18% gray card into the paint dealer and let them color-match it with their analyzer.

Was it $90 per gallon (http://www.rpimaging.com/store/manufacturers/gti/munsell-neutral-gray-paint.html)? No, but it wasn't ISO 3664:2000 compliant either.

I think this would be much too dark. I would definitely NOT want a room painted in 18% grey.

What you want is something lighter but still neutral. I purchased a Munsell N8 reference sheet, then took it to my local Home Depot where they color-matched it with Behr paint (flat). I don't remember the pigment mix they came up with, but this paint works really well on my print evaluation wall.

But depressingly drab. It does get to you after a while, if you are working in the same space five days a week. Really, go for neutral in a lighter tonal value.
