Color field with RGB color from DB

Hi everyone,

I am trying to make a Table which contains amongst other things a color colum.
the color colum contains a ID (varchar 255) which can be used to get the RGB (could be changed to Hex or something similar)
value from another table in the same database.
I want to color the field background with that color.
Is that possible in Grafan with standard tools or do I need a plugin for that?

There are about 60 colors, so working with thresholds would be a possibility, but a hassle to setup.

I found following topic, but it never got answered:
