Seems like the simple gauge is not accepting color variables? Is this normal? Other components like the icon seem to work.

Use `var(--seq-5)` instead.  
Also sometimes the inbuilt designer preview won't show it, so load it in a browser to test.

Yes, unfortunately. Most of the chart components are based on AMCharts (but I'm not sure if that includes the Simple Gauge) and they don't understand the CSS variables.

I solved the problem by creating a folder of session variables with the same names as the built-in themes and assigned the hex RGB values to those. Then you can bind the color property to the session variables. It became a bit more of a nuisance when the project had a light and dark theme and I had to create an expression binding on each of the session color variables.

I tried that, didn't work either.
