Whole-Room Paint Matcher
Undertone — the secondary hue bias hiding underneath a color — is usually what decides whether a paint clashes with your flooring, tile, or cabinets. That beige that looked perfectly neutral on the paint chip suddenly reads lavender once you've spent the money buying it and the time painting it — that's undertone playing tricks on your eyes. Fill in what's already fixed in your room below — real swatches show up immediately and narrow live as you go.

Color terms used on this page
Hue — the base color family (red, blue, yellow…), its position on the color wheel.
Undertone — the secondary hue bias hiding underneath, especially in "neutral" colors. It's what makes a gray read blue, green, or purple once it's on a wall.
Saturation (chroma) — how intense or pure a hue is, independent of how light or dark it looks.
Tint / Shade / Tone — a tint is a hue lightened with white, a shade is a hue darkened with black, and a tone is a hue muted with grey. All three can carry the same undertone as the pure hue underneath. More in the Color Theory Basics guide.

About these results
Color names and codes are trademarks of their respective brand owners. DigiTool Shed is not affiliated with or endorsed by any paint manufacturer.
Hue, undertone, and compatibility are computed from published RGB/HEX values using CIE Lab hue analysis — a useful guide, not a guarantee. Lighting, sheen, and your monitor all affect how a color actually reads in a room. Always confirm with a physical sample before buying paint.
Flooring, countertop, and cabinet reference tones are representative approximations of common materials, not scans of real products — a starting point for identifying your room's undertone, not an exact match.
