How to choose interior paint colors

Start with light, not the color chip

Natural light changes throughout the day, and a north-facing room reads differently than a south-facing one. Artificial lighting matters too: warm-toned bulbs shift colors one direction, cool-toned bulbs shift them another. A chip under store lighting can look noticeably different once it is on your wall at home.

Look for the undertone before you commit

Many colors described as "neutral" carry a hidden undertone, green, pink, gray, or blue, that only becomes obvious once the paint is next to your trim, flooring, or furniture. Holding a sample against the other surfaces already in the room is the most reliable way to spot an undertone before it becomes a surprise.

Test a large enough sample

A small paint chip is a starting point, not a decision. Painting a larger swatch, or a sample board you can move around the room, gives a much more accurate sense of a color than a chip ever will. Viewing that sample at different times of day, and on more than one wall, catches shifts a quick glance would miss.

Match sheen to the room

Sheen affects both how light bounces off a wall and how easy a surface is to clean. Kitchens and bathrooms typically call for a more washable finish, while flatter finishes suit bedrooms and formal living spaces where durability matters less than a soft, even look. Sheen also affects how visible small imperfections in the wall are, since higher-sheen finishes reflect more light.

Think about flow between rooms

Open sightlines mean colors in adjacent rooms are often seen together, not in isolation. Rooms next to each other do not need to match exactly, but a strong contrast right at a doorway can feel abrupt. Considering the view from one room into the next helps a color plan feel intentional rather than accidental.

Common questions

• Do I need to test paint samples on every wall? Not every wall, but testing on at least two walls with different light exposure is more reliable than judging from a single spot.
• How long should I live with a sample before deciding? Viewing a sample across a full day, morning, afternoon, and evening light, gives a more complete picture than a quick look under one lighting condition.
• Does sheen change how a color looks? Yes. Sheen affects how light reflects off the surface, which can make the same color look noticeably different depending on the finish.
