I think you should be able to accomplish this using a Custom Field Renderer and then implementing some “color picker” code (lots of example ways to create color pickers via google)

If you’re not familiar with using custom field renderers, you can check out the SKUID docs related to them here:
https://docs.skuid.com/latest/en/skuid/javascript/custom-field-renderers/

I’m not sure exactly how you’d go about setting up this specific example, but I’m sure this would be the right approach.

Depending on your SKUID version / setup, you might not have access to custom field renderers. If that’s the case you may need to reach out to SKUID to enable them.
