If you are painting white, cream, or beige... white primer is your best friend.
Common practice is to use a white primer or one tinted with the topcoat color.
Grey primer - This is the most common colour of primer used in most cars during their painting process, as it is the most neutral. This means that it has little effect on the shade of colour that you want, and is also very suitable for metallic-based paints.
For most colors, tinting the primer to a slightly lighter shade than the finish coat provides a better chance of reaching full coverage, and it helps you see where you've already painted your finish coat and where you still need to paint.
The easiest way to start picking the perfect primer for your needs is to take a look at your skin and figure out the color you are trying to eliminate. “Get on the internet, google a color wheel and start there. Opposites on the color wheel are the easiest way to determine the shade you need.
Conclusion. You can see that car primer color plays a significant role in how your car's paint dries. Darker primers yield deeper, darker colors, while a white primer gives you bright hues. Now that you know how primers affect your final paint shade, pick a primer that fits your paint color and get to work!
--For covering up walls that are dark, or rich in color, a gray colored primer works best. This hides the tone of the color underneath best. With a white primer you will need 2-4 coats of primer, to cover blacks, and reds.
The best primer to cover dark paint depends on the final look you want to achieve. If you intend to paint the walls a light color, use a white primer. If you want the base coat to be similar to your final wall color, use a tinted primer or add paint to white primer.
Like prepping walls before a paint job, primers help fill in fine lines to create a smoother surface, so makeup glides right on. The new tinted versions have added benefits: A pink hue gives luminosity; yellow tones down ruddiness; purple brightens and reduces sallowness; and peach cancels out hyperpigmentation.
For long lasting durability be sure to apply two coats.
Primer is typically an off-white color. Many paints achieve their true color—and in fewer coats—when applied over this kind of primer.
As a general rule, it's always best to prime, but there are times when you may be able to get away without it. Such circumstances might include painting a similar colour over walls that are already clean, painted, and sealed. Or perhaps when updating from a lighter colour to a darker colour.
You probably don't need a primer. If the current wall is smooth, clean and covered with the same type of paint (both are oil-based for example), you can head straight for the paint. You need to fill holes, spackle and sand*, maybe even cut a new piece of drywall in to the existing wall.
Most projects where you're going over a previously-painted surface do not require the use of a primer. In many cases all you'll need to do is spot-prime any bare areas that need to be addressed before applying your finish.
You will want to use 2-3 coats of primer to ensure there is a good bond between the new paint and the wall, and also to cover up any previous colors, especially if they are red, orange, or a strange outdated color. In short, you will typically need 2 coats of primer for most painting projects.
In most situations, a good rule of thumb is to use a primer plus two coats of paint. If you use this rule, you may do one more coat than needed but this won't hurt the final product. There are few situations where this rule of thumb will result in doing too few coats though which is why it is prevalent advice.

Some say the primer color does not matter, and it doesn't if you put enough coats over it. However, that can get costly, and many people don't want to spend more money on paint than they have to. Spray primers (in aerosol cans) and surface primers (which you can airbrush or brush-on) come in many different colors.
Types of Primers. There are three basic types of primers: oil-based, latex and pigmented shellac primer. Each has its strengths and weaknesses and works best on certain surfaces and in particular circumstances.
Latex-based Primers: As water-based primers, they are perfect as the first coat on drywall or softwood. These are typically fast-drying, easy to clean, and are a healthier variant of primers owing to the low VOC. Shellac Primer: They are an ideal interior wall primer if stain-blocking is a priority for you.

The basic difference between paint and primer is that paint is typically made up of resins pigments whereas primers are resins. The primer's basic function is to provide a sealed and stable surface for your topcoat (paint) and the resins contained in primers seal porous surfaces and provide that bond to the surface.
Shellac is the oldest and strongest type of primer. It's the best type of primer for sealing stains be it water damage, rust, or smoke (and yes it covers the smell too). It's also highly versatile so you can use it on wood, metal, drywall, plaster, and even plastic making it a great catch-all.
