Frequently asked questions
How does this hex-to-Pantone tool choose a result?+
It parses one three- or six-digit HEX color and selects the smallest squared RGB distance among only five bundled samples: Black C, White, 186 C, Process Cyan C, and 354 C.
Which inputs and controls are available?+
There is one hex-color text input and Run locally. No Pantone library selector, book edition, substrate, illumination, tolerance, spot-ink proof, image picker, export, or batch mode exists.
Which limits matter?+
This is not a complete Pantone library or a print proof. It compares raw RGB Euclidean distance only, not Lab/Delta E, ink recipes, color management, paper, display, or production conditions. Invalid hex throws.
What result should the documented example produce?+
For #000000, the nearest entry in the small bundled sample palette is Pantone Black C with RGB [0,0,0]; it is not a full Pantone library or print proof.
