I have an existing beige color in the walls of my house. I am getting them repainted and following suggestion from my painter I went to the store - got sample of sherwin williams accessible beige. I also bought a plain white board to try the color as well.(The eventual paint would be promar 200 from sherwin williams)
So i have put two coats on the plain white board and two coats on the wall as well. The problem here is with the same light - the 2 coats on the wall look more whitish and different from the color on the white board. The coats on the white board look more close to the real color that is advertised. The painter thinks its due to the existing wall color (beneath the two coats of the sample) changing the eventual color. he says he can put a primer beneath but that would mean 3 coats and more money expense to me.
So I had few questions:
Is it correct that the color beneath the 2 coats is making a difference in how the walls look?
Is it possible to use some other product which would give a result true to the advertised color in 2 coats. The existing color on the walls is not dark enough to warrant 3 coats, I feel. Should i go for benjamin moore? I do not know why my painter advocates sherwin williams while i have always heard benjamin moore being the best.
In the pic in this link, the background color is my existing color. I have painted a small part of the wall and i am also holding the white cardboard with the 2 coats of paint.
