Yes. The example

https://github.com/ngtk3/nim-gtk3/blob/master/test/colors.nim

is dynamically, I used it to generate some color schemes. Entered color
hex value in a text entry widget, and that color was applied.

As I said, it was working for 3.18. I think for 3.20 and above some CSS
names have changed, I had not the time to really investigate that.

I have no C code currently, I think my Nim code was inspired by Python
code, but I have no link to that python code currently. For C it is the
same pattern -- generate a CSS string and apply it.
