Any tools or utilities to match colors in a 3mf (or from a hex code) to Bambu Lab filaments?

I'm looking into printing a pixel puzzle that has a lot of different colors involved. I'd love to be able to pick a color in the 3mf, or at least use a color picker tool to get the hex code, and get the nearest match to Bambu Lab's filaments so I can at least use them as refills. I know that filamentcolors.xyz exists but it's not quite a color code matcher.

Does such a tool exist?
