Paint Color Converter
Coverage. The generated directory contains 7,591 unique brand+official-code records: 1,726 Sherwin-Williams, 4,056 Benjamin Moore, and 1,809 Behr. Separate manufacturer modules preserve attribution; equal or nearly equal RGB/HEX values remain separate when their official brand/code differs.
Sherwin-Williams source. Generated from the official ColorSnap Color Information spreadsheet (1,526 rows) and Emerald Designer Edition Digital Data spreadsheet (200 rows). The published fields include official name/number and RGB/HEX, with locator, collection/category, or LRV fields where supplied. Official downloadable color palettes and Color Information files.
Benjamin Moore source. Generated from nine official downloadable ASE palettes: Affinity, America’s Colors, Classics, Color Preview, Color Stories, Designer Classics, Historical, Off White, and Williamsburg. Each ASE swatch supplies the official code/name and sRGB values; NumPad derives HEX exactly from those RGB bytes. Official Benjamin Moore palette downloads.
Behr source. Generated from Behr’s official colorchips-2-10-2020.zip download supplied by the project owner. It contains 1,809 single-color 250×250 swatch images organized by family; the official filename supplies code/name, the uniform image pixel supplies RGB, and NumPad derives HEX exactly from RGB. The package date is retained because it may include historical entries. Official Behr downloadable palette page.
Generation and maintenance. Rows are generated from the cited first-party files rather than copied into the page component. Validation rejects missing code/name/color fields, non-uniform Behr swatches, RGB/HEX inconsistencies, and duplicate brand+code keys. Refreshing the directory requires rerunning the same import against newly published manufacturer files; NumPad does not silently scrape or merge third-party color lists.
Matching pipeline. A validated sRGB input is linearized, converted to CIE XYZ and then CIELAB using the D65 reference white, and compared with stored swatches using CIEDE2000 (ΔE00). Catalog Lab values are cached by stable record reference after their first conversion so later searches do not reconvert the full catalog. A smaller score means the stored digital swatch is numerically closer under this model. It does not establish visual identity, formula equivalence, or manufacturer approval.
Real-world limits. Screens do not reproduce physical paint exactly. Lighting, surrounding colors, sheen, substrate, preparation, application, coating thickness, aging, and manufacturer formula changes can affect appearance. Always verify the exact manufacturer name/code and test a physical chip or painted sample in the intended space.
