More colour in custom parameters

is there a way to have more colour control, or options within the custom parameters for master colours? if I want to set a dark navy blue background and a golden yellow letter, I can’t, the letter colour defaults to grey

The color of the background and letters can be changed in the appearance settings:

You mean like this:


Because the background is so dark, the edit view switches to “Dark Mode”. So you need to add a “Master Color Dark”.

The preview below the edit view doesn’t seem to pick up the master colors. I’ll look into it.

profuse apologies, I had forgotten about the extra options for dark mode, I now have what I wanted, thank you
