Spot Color Approximation Tool
Find the closest match to a color in a small, generic reference swatch library — an approximate starting point, not an official spot-color match.
Overview
Spot Color Approximation Tool finds the nearest match to your color in a small, hand-built library of generic reference swatches, along with the perceptual color difference (ΔE) between them. It's deliberately not built on Pantone, RAL, or any other proprietary spot-color system — those require a license to redistribute — so results should be treated as an approximate starting point, not a final print decision.
Key Features
- Finds the nearest match in a generic, open reference swatch library
- Shows the perceptual color difference (ΔE) between your color and the match
- Explicitly not Pantone, RAL, or any other licensed spot-color system
- Deeplinkable via a ?hex= URL parameter
Common Use Cases
- Getting a rough print reference — Find a generic named reference close to a brand color before a print conversation with a vendor.
- Describing a color without a swatch book — Get a plain-language reference name and distance for a color when you don't have an official swatch book on hand.
How It Works
Enter a color
Type or pick the color you want an approximate match for.

The closest match in our generic swatch library appears, along with the perceptual distance (ΔE) between it and your input.
Use it as a starting point
Treat the result as a rough reference, not a final spot-color decision — confirm any real print job against your print vendor's actual swatch book.
