Flat has a chalky appearance in finish, absorbs light, and can make a color look slightly lighter. Semi-gloss/gloss will make a color look darker. The sheen will reflect the light, causing the color to be darker. Matte or eggshell usually the most true to color when considering finish.
Eggshell paint dries lighter because it has a more matte finish. While it has a lighter appearance than gloss finishes, it is darker than flat finishes. It also has a bit of sheen but less than semi-gloss paint finishes.
If you use eggshell paint and aren't abusive to your walls, it can easily last a decade and still look great. If you use flat paint, your walls will likely look shabby after just a few years. For the end user, it's ultimately better. Eggshell paint just looks richer than flat paint.
Eggshell paint reflects more light than matte to produce a low luster. This low luster pulls out more of the paint's color than a flat sheen and it gives the room a soft glow.
We recommend matte paints for bedrooms and as living room paint finishes where the walls are exposed to less moisture, choosing a glossier eggshell finish for kitchens and as a paint finish for bathrooms, which are more prone to moisture, as well as children's rooms, which might need more regular cleaning.

If your wall has imperfections like uneven texture, patches or joints, flat paint will absorb light and make them less noticeable. However, flat finishes are not very durable and need to be carefully cleaned. Scrubbing flat paint could wear down the finish and cause sheen to appear in patchy spots.
You should be using flat paint on walls and areas that have a lot of bumps, scratches, or holes. Since it can conceal these blemishes easily, it'll be the one paint finish you'll want to be using. It's best for low-traffic rooms that have a ton of light like offices and more formal rooms, like dining rooms.
Flat has a chalky appearance in finish, absorbs light, and can make a color look slightly lighter. Semi-gloss/gloss will make a color look darker. The sheen will reflect the light, causing the color to be darker.
Poor quality of some trades, like drywall contractors, or framers, can make imperfections pop out if there is a sheen in the paint. Using flat paint keeps imperfections from being so noticeable.
An eggshell finish has a subtler shine to it, so it's a great choice if you're not ready for satin. It offers what you may expect - it's shinier than flat (but not as glossy as satin), and it's easier to clean than flat (but not as easy to clean as satin).
Flat and Matte finish paints are ideal for covering walls that have flaws or blemishes. Even larger imperfections, such as extensive scuffs and nail pops can get covered and camouflaged since Flat Paints are effective at absorbing light, in essence, “hiding” the bumps and lines that exist on every wall.
The mistake, then, is choosing a flat finish for your bathroom walls. In terms of the actual paint finishes, Consumer Reports recommends using either satin or semi-gloss. They argue, "Satin is more durable and shinier than eggshell and is ideal for a bathroom. It's also easy to clean.
It depends on the surface you are painting. For interior walls in high-traffic spaces like a mudroom, satin or eggshell finishes work best. Flat or matte finishes work best for most ceilings and semi-gloss is recommended for interior trim and doors.
Finishes may go by different names depending on the paint brand, but there are basically three standard types: Flat/matte, eggshell/satin, and semigloss/high-gloss, which is sometimes referred to as pearl.
Matte and Flat
These paint finishes deliver a smooth, subtle look and show little to no sheen when dry since they absorb light. Pros: Matte and flat finishes cover imperfections in surface and application, making them a great choice for ceilings as well as walls in the bedroom, dining room and living room.
Low sheen paints are the most popular finish because they are easy to clean and are more durable than the flatter finishes. The slight sheen level can highlight any surface imperfections but are an ideal choice for walls in high traffic areas.
If you cannot see any light bouncing off the finish of your painted wall, you have flat paint. Unfortunately, flat paint is much quicker to show scuffs, smudges, and fingerprints than other types of paint finishes. It does not hold up well to moisture, which is why it is seldom used in kitchens and bathrooms.
Even if paint is not actually scraped away or scratched off, the color can be harmed by abrasion, especially on low-sheen finishes such as flat and matte. The problem is that low-sheen finishes contain microscopic hairs which stand on end and absorb light so that the surface does not reflect.
Satin and low-lustre paints have a slightly higher sheen than eggshell finishes. Paints in this category are warmer and provide a greater appearance of depth than flat paints. They also resist stains better than flat paints.
Glossy paint will typically make a color look darker because the sheen will reflect the light, causing the color to be darker. Eggshell or Matte generally stays very close to the swatch color because it neither reflects nor absorbs light.
Matte paint reflects less light than satin so it offers a uniform look with good coverage and strong color. It will be less easy to clean and isn't as durable however, so keep it for less busy areas of the home.
Does Paint Dry Darker or Lighter? Paints typically dry darker, particularly oil, acrylic, and latex paints. However, that doesn't mean it will look different than what's on the paint swatch. If you mix the paint properly, it should look the same as the color you picked out once it dries.
Walls: We usually prefer to do two coats of paint on all walls whether or not we're using a paint and primer product. Why? Because it's far more difficult to mask flaws, even with flat paint, on an area as broad as a wall. Also, if we're using anything but flat paint, then a second coat is required.
Generally, you will want a minimum of two coats of paint – this is a good rule of thumb for any wall or ceiling you're painting. You'll rarely get a seamless finish from just one coat of paint, and even if you do, coverage isn't the only goal when it comes to painting a room.
But flat paints can be hard to clean since their porous texture can trap dirt and grime. And since flat paint doesn't resist water like glossier paint does, cleaning it may leave behind unwanted streaks that can make an already dirty wall seem even worse.
