Will painting over a dark color wall change the color of the new paint?

Question

I have just painted my daughter's room apple green although I had wanted a more olive green. The color chosen didn't turn out how I had wanted it to be (olive green). Now I am wanting to repaint it to the olive green but after testing new intended color on white walls AND also on the apple green walls, it turns out that the results differ although I have using the exact same paint. The one painted on the apple green has a mustard tone while on the white walls, it is what I want. How do I solve the problem?

Answer 1

Prime first - this is the only way to gain consistency and control.

Answer 2

Paint is not actually opaque. Like printing inks, they are partially transparent and they get part of their colour from what lies underneath. This is the point of primer paints, which are opaque, and are also tinted for use with dark colours. A room that will be painted deep red has primer that looks like bubblegum!

So the colour you're not aiming for is a product of the underlying apple green and the overlying colour. It would be tricky to match the colour of the paint on the white wall to that altered shade, but if I understand you correctly you want all the walls to look like the previously white wall does. Is that right?

If so, buy some primer and cover the previously painted wall white. Then paint the new colour on that, and the walls will match.

Good luck! If you have any problems drop me a line.

Answer 3

Paint over the apple green with a primer which is a white colored paint before you use the paint you want. It does not have to be a perfect paint job when applying the primer just so your walls are white. The primer dries quickly so you will not waste too much time. Don't be cheap buy a good quality primer I suggest a brand called zinnser( spelling?)

Answer 4

I think the olive paint looks like mustard in relation to the apple green. The blue in the apple green will pull out the yellow in the olive green making it appear that it is different. Once the entire wall is covered so you can't any apple green it won't look so yellow.

Answer 5

If the paint is wet, wait for it to dry. If it is dry, the color underneath is bleeding through so you probably need to use white primer before you paint it olive.

Answer 6

It sounds like you didn't use primer first so your result is the bleeding through of the original color. If you want to redo, prime first, let it dry, then paint.
