So you've got a color palette in Figma and you've used the Figma Tokens plugin to export that palette to JSON. This little utility app renders your palette and search for the nearest palette match for any given hex code.
If you'd like to bring your own data, just replace the data/color-tokens.json file with your own Figma Tokens export - as long as it matches the existing schema you're good to go.
