The dark mode colors that are currently part of LyX 2.4 are hard coded. 
You can see them here:

https://www.lyx.org/trac/browser/lyxgit/src/Color.cpp

There you will find a comment

//  ColorCode, gui, latex, x11hexname, x11darkhexname, lyx

So, for example,

{ Color_footlabel, N_("footnote label"), "footlabel", "#00aaff", blue, 
"footlabel" }

means that the color "footlabel" will be set to "blue" in dark mode. So, 
without dark mode support, this corresponds to the following line in the 
Preferences file:

\set_color "footlabel" "blue" "blue"

(Setting the light mode color to the same color as the dark mode color.)

In this way you should be able use the same colors in the work area (!) 
that LyX uses where it supports dark mode.

Granted, it is a bit cumbersome to transfer all the colors.

It might be a good idea to add a button to the color dialog for manually 
switching to dark mode/light mode colors.

Hope that helps!
