Because of this, it's essential to pick the right paint color for your space. Location, functionality, and the overall look and feel you're going for are all key considerations. According to Elle Decor, a home remodeling and design organization, who shared an experts insight, painter Sarabeth Asaff South, "There are undoubtedly a lot of things to take into mind. You should pay great attention to all of these aspects since they may have a subtle effect on things like paint gloss and saturation."
Before anything else, don’t forget the primer.

Primer
When you're ready to paint, you'll want to use primer, but don't mistake it for actual paint. Before painting, using a primer serves as an adhesive for the color, making the painted surface longer and more durable.
Primers are a must for newly cleaned and unpainted surfaces. Priming is essential if you're painting over an already dark paint hue. Although multiple coats of paint may be required to fully cover a deeper tint, just a thin primer layer is usually required. Primer is often less expensive than actual paint, saving you money in the long run.
There are different types of finishes you can use in your house:

Flat/Matte
Nail holes, for example, maybe easily concealed using flat paints, which often only take one or two applications. To avoid damaging them, utilize them in low-traffic places like dining rooms or on surfaces that won't be touched as frequently as the ceilings, such as walls. Flat paints, often known as matte paints, have the lowest sheen.
Suitable For: Low-traffic areas, such as an office or a formal sitting room, with plenty of natural light

Eggshell
Eggshell paint finishes are pretty popular. Unlike flat finishes, they are glossy with a subtle sheen like an eggshell, conceal defects, and are more durable. Like living rooms, corridors, and entryways, eggshell paints are ideal for low- to medium-traffic areas like these.
Suitable For: Typical living and sleeping quarters.
