What is the Grout color selector?
The Grout Selector helps architects, interior designers, and contractors choose the perfect grout color for tile installations. Upload a tile image or enter a URL, and the tool automatically extracts the dominant tile color to recommend matching, contrasting, or neutral grout options from major brands.
Select from Mapei, Laticrete, and Custom Building Products (CBP) grout colors. The tool uses advanced color matching algorithms (Delta E 2000) to find the closest grout matches and complementary contrasting options. Get precise material coverage calculations based on tile dimensions, joint width, and area.
Whether you're designing a bathroom, kitchen backsplash, or commercial floor, the Grout Selector takes the guesswork out of grout selection and ensures you order the right amount of material.

Frequently asked questions
Mapei (Flexcolor CQ, Ultracolor Plus Max), Laticrete (PERMACOLOR Select), and Custom Building Products (Polyblend). Each brand offers 15+ popular grout colors.
The tool uses Delta E 2000 color difference algorithm—the industry standard for perceptual color matching. Delta E < 1 = excellent match, < 2 = very good, < 3.5 = good.
Unsanded: joints < 1/8" or glass/metal tiles (prevents scratching). Sanded: joints ≥ 1/8" (provides structural integrity and prevents shrinking).
Use the TCNA formula: Lbs = ((Tile L + Tile W) × Tile Thickness × Joint Width × 1.58) / (Tile L × Tile W) × Area. Enter tile dimensions, joint width, and area in this calculator to get bag counts.
This tool includes Custom Building Products (CBP) grout colors and coverage calculations. Select CBP in the brand filter to see Polyblend and other CBP grout options with color matching and material estimates.
