Customize Data Coloring Based on Data

Hi, I need some help.

I have data that involves colors. For example, imagine I have a table with the following structure:

ItemId Color Color_Code_Hex
189987dfs897shs9df White #000000
s98dfb7bsd87f687sd Black #FFFFFF
8df786gd87f6g8d7f6 Red #FF0000

I would like to plot a bar or donut chart where we count the unique ItemId’s per Color, and I want each bar/slice to be painted in its corresponding color (so the count of Red items should be painted Red, and so on).

Is there any way to do this in Looker?

Thanks!
