Primer paints may be oil- or water-based and are used to seal unpainted surfaces to prevent covering coats of paint soaking in. The appropriate type of primer should be used for the surface being painted - wood, metal, plaster or tiles. There are some 'all purpose primers' available which are designed for two or more of these surfaces.

Remember this simple rule when thinking about Warm or Cool: Warm individuals have red or gold highlights in their hair. Cool individuals have no red or gold highlights in their hair. That is true for girls and women of all ages. Whether you color your hair, use the color you have now as the basis to determine whether you are Warm or Cool. Congratulations! You are half way towards determining your Season.

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.
