How to choose interior paint colors you won’t regret

The surest way to choose interior paint colors you won’t regret is to start with what is staying in the room, match undertones to it, and test real samples on your own walls before buying gallons. Look at those samples in morning light, evening light and under your own bulbs. A color that still looks right at all three times is a safe choice.

Most paint regret comes from picking a color off a two-inch chip under store lighting. The chip is accurate; the conditions are not. Your room has its own light, its own floors and its own furniture, and every one of them changes how a color reads on the wall.

Where should you start when you choose interior paint colors?

Start with the things you will not change: flooring, countertops, cabinets, stone, large furniture and rugs. Paint is the easiest surface to adjust, so it should fit those fixed pieces, not the other way around.

Pull a sample of each fixed material into one spot, or take a photo of them together in daylight. Note whether they lean warm (yellow, orange, red) or cool (blue, green, gray). Then decide how much of the room each color will cover. Sherwin-Williams teaches the classic 60-30-10 rule: feature 60% of your main color, use the next color half as much, and finish with 10% of a color for small accents.

In a typical living room, that might look like this:

• 60%: walls in a soft main color
• 30%: trim, a large sofa or built-ins in a supporting color
• 10%: pillows, art, a front door or one accent wall

Thinking in proportions keeps a bold color you love from taking over a whole room, and it gives you a plan before you ever open a can.

What are paint undertones, and why do they matter?

An undertone is the subtle color sitting underneath the main color, such as the green inside a gray or the pink inside a beige. Undertones are why two “neutral” colors can clash and why a gray can look blue once it is on the wall.

The easiest way to see an undertone is to hold the chip against a sheet of plain white paper, then next to colors from the same family. The hidden color jumps out by comparison. Undertone also interacts with your light. For north-facing rooms, Sherwin-Williams recommends avoiding cool undertones and choosing a warm neutral or a color with warm undertones, because those rooms get the least light during the day.

How does the direction a room faces change a paint color?

The direction a room faces controls the color of the daylight coming in, and that light tints every wall. The same paint can look warm in one room and cool in the next.

Sherwin-Williams breaks it down by orientation. North-facing rooms receive the least light, so you’ll want colors with a higher LRV. South-facing rooms experience consistent warm light throughout the day, so very warm colors can feel bolder than expected. East-facing rooms get warm light in the morning and cool light toward evening, and west-facing rooms do the opposite.

A quick guide for Owensboro homes:

• North-facing: warm neutrals and lighter colors to offset cool light
• South-facing: cooler or softer colors so warm light does not overpower them
• East-facing: pick for the time of day you use the room most
• West-facing: expect evening glow, and test samples late in the day
• Few windows: base the choice on the bulbs you use

What does LRV mean on a paint chip?

LRV stands for light reflectance value, a number that tells you how much light a color reflects. Higher numbers make a room feel brighter; lower numbers absorb light and feel darker and cozier.

Sherwin-Williams measures LRV on a scale of 0-100 with zero reflecting no light and 100 reflecting all light. Its color guidance also notes that lighter tinted paints have higher light reflectance values than darker ones, which is why LRV matters most in rooms without much natural sunlight. Check the number on the chip or the color’s product page before you commit.

Sheen changes reflectance too. Sherwin-Williams explains that the higher the gloss level, the more light bounces off the surface, and that higher gloss paints tend to enrich and brighten color. Sheen choice by room is its own topic, covered in our interior painting prep guide.

Do light bulbs change how paint colors look?

Yes, a lot. Warm bulbs push walls toward yellow and dull cool colors, while cool bulbs make blues and greens pop and flatten warm colors.

Sherwin-Williams describes incandescent bulbs as generating yellow light that intensifies warm colors but tends to dull cooler colors, while fluorescent bulbs give cool, blue light that amplifies blues and greens. LED bulbs come in both. The U.S. Department of Energy explains that light color is measured on the Kelvin scale, and that higher K numbers mean the light appears cooler while lower numbers look warmer. Since 2011, the Federal Trade Commission has required a Lighting Facts label on bulb packaging that lists light appearance, so you can check the box before you test.

The practical rule: test paint under the bulbs you actually own, and keep bulb color consistent within a room. Mixing a warm lamp and a cool ceiling fixture makes any color look uneven.

How should you test paint colors before committing?

Test at least two or three finalists as large samples on more than one wall, then live with them for a few days. Small swatches side by side on one wall trick the eye.

A simple testing routine:

• Paint or stick samples at least the size of a sheet of paper
• Place one near a window and one on the darkest wall
• Put each sample next to trim, flooring and furniture
• Check morning, midday and evening, with lamps on at night
• Remove the samples you reject so they stop influencing you

Timing matters because light changes through the day. Sherwin-Williams notes that east-facing rooms get warm light in the morning and cool light toward the evening, so a sample that looks perfect at breakfast may read differently at dinner. If you are planning a bigger change, such as repainting kitchen cabinets, test the wall color against the new cabinet color too.

How do you choose colors that flow from room to room?

Pick one family or one undertone for the main living areas, then vary the depth rather than jumping between unrelated hues. Rooms you can see from one another should look related.

Sherwin-Williams lists four ways to build a palette: complementary, split-complementary, analogous and monochromatic. A monochromatic palette uses tints and shades of a single color and is ideal for enhancing perceived space, which suits open floor plans. Analogous colors sit next to each other on the color wheel and create harmony. Save stronger contrast for spaces with a door you can close, such as an office, powder room or bedroom.

Using one trim color through the whole house is the easiest way to tie different wall colors together. It also simplifies future touch-ups. The same idea carries outdoors: if you are refreshing siding, shutters or a front door, our exterior painting team can pick an entry color that works with the rooms just inside.
