How do I change the colors of the order book and the level lines?

Question

Accepted Answer

In “Theme and colors”, set “Bid color” and “Ask color”, and separately “Bid level-line color” and “Ask level-line color” (the “Reset to auto” button returns the calculated color). “Level lines opacity” and “Level lines thickness” are set with sliders. Changes show right away; “Save” writes them to the theme file.
