When it comes to rolling out the walls never ever use a cheap foam roller. Foam rollers never evenly absorb the paint out of the pan and will actually add time to you project and cause more mess. Buy yourself a synthetic professional 3/8 nap roller head for about $6 to $8. Not only will the paint be applied in a smoother fashion you will experience less work and mess.
What colors are prevailing - tonal or local, warm or cold?
Purple is the most contradicting color, to start at least because it consists of two antagonists: hot red and cold blue, ice and fire. It is the most mysterious color. It was the last color to emerge in art. Purple has a lot of other shades that are less rich and more lightened and muted: starting from light-lilac and going up to ashy gray-purple, which can give the interior a certain style and exquisiteness.
PRIMARY COLORS. The primary colors are red, yellow and blue. These colors are your base colors from which all other colors come from.
Treat yourself to a good lunch and forget the diet. It is amazing what some pizza or a good burger will do for the afternoon painting push.
However, if you put a coat of pure white primer (which has a score of 0) on top of the brown color wall first, this immediately brings your luminosity score down to 4 (8 + 0 = 8/2 = 4, the average). This means you may only need one coat of yellow paint to give you the right hue and saturation. In reality of course, you will always want to do at least 2 coats. But even with a total of 3 coats (primer and paint) you are way ahead of the paint-only option.
On the other hand, in some cases there are legitimate reasons for one area to be bad even if the rest of the paint is solid. If poor body work or rust repair was done in the past then maybe just that section of paint will need to be removed.
