How to use the room color scheme builder

Build a room color scheme by assigning colors to the walls, trim, floor, and accents. Use the preview to see how your selected colors work together before you decorate or paint.

  1. Enter or choose a color for the walls.
  2. Assign a color to the trim.
  3. Choose a floor color.
  4. Add an accent color.
  5. Review the room preview and adjust the colors until the scheme fits your room.

What to enter

Walls
Set the main wall color for the room.
Trim
Set the color for trim and other edging.
Floor
Set the floor color.
Accents
Set the accent color for smaller decorative elements.

Example: Build a warm, nature-inspired scheme

Choose a light neutral for the walls, a darker neutral for the trim, a wood-like brown for the floor, and a muted green for the accents. Review the preview to see how the four assignments appear together, then adjust any color that feels too strong or too similar.

How the room preview works

The builder applies your selected colors to four room elements: walls, trim, floor, and accents. It then displays those assignments together in a visual preview so you can compare the overall scheme and change individual colors.

Reading the results

Use the preview to judge the relationship between the large surfaces and smaller details. The walls and floor have the greatest visual area, while trim and accents can add contrast or repetition. The preview is a planning view, not a representation of a specific paint or flooring product.

Limitations and common mistakes

  • The preview does not identify paint-brand colors or product names.
  • Screen colors can look different from physical paint, flooring, and fabric samples.
  • The tool assigns one color to each room element; it does not model different walls, flooring zones, lighting, or room dimensions.
  • Check physical samples in the actual room before buying materials.

Frequently asked questions

How do I choose colors for a room?

Start with the largest surfaces, such as the walls and floor. Then use trim and accents to add contrast or repeat a color already used in the room.

Should trim match the walls?

The builder lets you assign a separate trim color so you can compare a matching, lighter, darker, or contrasting option in the preview.

Can I preview wall, floor, and accent colors together?

Yes. Assign colors to the walls, trim, floor, and accents, and the preview shows the complete combination together.

Does the preview show exact paint colors?

It shows the colors you assign on screen. Lighting, materials, and display settings can change how those colors look in the finished room, so compare physical samples before purchasing.
