fast background color

I’d like to use hex code for background color with very few keystrokes. I know how to do it with Background Color → Custom Color. I tried defining a shortcut key for that but it didn’t seem to do anything How can I do this?

I do not know any way to go directly to the custom colors (where the hex code is specified) with a keyboard shortcut.

I’m assuming that you do not constantly need changing colors. Since it would be easier, you create your own color palette. How you can create your own color palette, you can read here in the TDF Wiki. On this wiki page you can also download two finished color palettes.
