Find the nearest color inside your own list
When you already hold a brand swatch set or a list of approved colors, judging by eye which one a new HEX belongs to gives a different answer every time. Enter one target color and your reference list, and the page ranks up to five of the closest entries by distance. Only the colors you enter are searched. Start each line with a HEX code and put a name after it, and that name comes back in the result.
Why there is no built-in Pantone table
Pantone color numbers and their values are proprietary material held under a paid license. Adobe itself removed the Pantone libraries from its products in 2022 over license terms. There is no one to one mapping in principle either. HEX and RGB add light, while Pantone mixes ink, and spot inks such as neons, pastels and metallics sit outside the sRGB gamut and cannot be shown on a screen at all. So this page carries no number table. You supply the values you read from your own licensed material or physical swatches, and the math happens inside that list.
How distance is computed
The default converts both colors to OKLab coordinates as published by BjΓΆrn Ottosson, takes the Euclidean distance across the three axes and multiplies by 100. A plain sRGB distance is offered as a comparison. Whichever one runs is always printed with the result. CIEDE2000 is not used here, as its formula is long enough to get wrong. A smaller value means a closer color, and no pass threshold is claimed. Current as of October 2026.
Frequently Asked Questions
No. Pantone numbers and values are licensed material, so a free tool cannot carry the official figures, and ink and screen work on different principles with no one to one mapping. Put the values you read from your own licensed material into the reference list and the page finds the closest entry inside that list.
The OKLab default is the better choice. It is built so that equal numeric steps correspond more closely to equal perceived differences. The sRGB distance is simpler to compute but understates differences in the darker part of the range.
This page does not state such a line. Acceptable tolerance depends on the print process, the screen and the material, and it is set in your own workflow. Use the ranking and the numbers to compare within your list.
