Color Snap Tool

This tool computes color matches by taking a user-provided color value (hex or RGB) and locating the closest Sherwin-Williams swatch from a canonical deck. It delivers an objective match based on perceptual color distance, helping users plan repaint projects, coordinate palettes, and communicate color decisions with clients or trades.
Conceptual workflow: inputs are converted to CIELAB, swatch colors are likewise converted, and a distance metric (Delta E2000) is computed for each swatch. The minimum distance determines the closest color. If multiple swatches are near-tied, the tool applies a secondary rule (favoring slightly warmer hues or higher saturation) or returns the top N candidates when requested. Outputs include the swatch name, hex, RGB, and the calculated Delta E.
Audience and value: interior designers, contractors, paint retailers, and homeowners use this to reduce guesswork, speed approvals, and ensure visuals align across lighting scenarios and materials. It also supports design documentation by exporting color data.
Unique differentiators: official deck alignment, perceptual distance using Delta E2000, deterministic nearest-match algorithm, tolerance parameter, and structured outputs that integrate with design workflows. Limitations: color perception varies with lighting and finishes; this tool does not simulate these effects; results should be verified in real swatches.
