Paint Color HQ is an online resource for discovering, comparing, and planning with paint colors. Its catalog brings together more than 26,000 shades from 13 paint brands, including Sherwin-Williams, Benjamin Moore, Behr, PPG, Valspar, Dunn-Edwards, and Farrow & Ball. Visitors can search by paint name, number, or hex code, browse color families, and explore curated palettes and inspiration.

The site offers practical tools to help users make informed choices before buying paint. These include a room visualizer for previewing colors on walls and trim, a photo color identifier, a palette generator, cross-brand matching, undertone analysis, side-by-side color comparison, and a paint calculator that estimates gallons from room dimensions, coats, and door and window cutouts. Its articles provide color details, coordinating suggestions, undertones, and cross-brand matches.

Paint Color HQ describes its service as free and available without signup. Color information is based on manufacturer-published digital values, so the site advises testing physical samples, since paint formulas, finishes, and lighting can affect how a color appears.
