Paint should not be applied to a concrete basement floor until the concrete has aged for at least a year. The floor should be dry when painted, the best time for application being during the winter or early spring (assuming there is some heating apparatus in the basement), when the humidity in the basement is low. In general, three coats of paint are required on an unpainted floor, and the first coat should be thin to secure good penetration. After the paint is dry, it should be protected with a coat of floor wax. Obviously, when mistakes like this occur paint companies have nothing to lose. Whenever people pick paint colors that they are unhappy with, the paint company does not have to refund the customers' money. In fact, no paint brand in the country will allow you to return paint once you have purchased it. Even better (for the paint company), since the customer is unhappy with the paint color they chose, they are probably just going to buy a whole new batch of paints! Definitely good inside the house is a new vinyl primer-sealer to be used as a base coat under any paint. It dries in as little as 30 minutes.
Proper rolling technique: When rolling paint on the wall, get the roller skin evenly loaded with paint and make a V,N or M pattern on the wall, this is to spread the paint across the entire section you will be rolling, then roll back across the section and even out the paint. To properly "lay off" each section, make a final pass of the section applying light pressure to the roller frame arm end of the roller skin and bringing the nap mark (mark created on the pressure applied side of roller skin) across from the beginning of the section to the end of the section, and just repeat all the way down the wall.The V,N or M pattern, will be determine by how far the paint will spread, a V is for less spreading paint and M is for farther spreading paints. Do not "dry roll", which means trying to roll to much of a section at once with very little paint on the roller. Just as important, do not apply to much, if you find you are applying to much, increase the size of the section you are painting i.e. from a V pattern to an N or a N pattern to a M.

In our first case, if you decide to paint a wall in your house with a light yellow color, but the wall is currently a deep dark brown, you will go through bucket after bucket of paint trying to cover that brown, easily doing 4 - 6 coats or more. But if you put down a coat of white primer first, you could be done after 2 coats of paint.
