I searched the Help->Browse Manual for "color" and came up with SetBackground. Set passed 24 bit number as RGB color of background. which is cryptic to say the least it means (d-SetBackground 0) would set the background to black. (d-SetBackground #x00ff00) turns red and blue off etc. There is a Denemo procedure to get a color from the user, too. (d- SelectColor) which returns a list of r, g and b values in range 0.0-1.0 that would need converting to use with d-SetBackground. HTH Richard

It'd be nice to be able change the background colour of the Denemo Display.

Yes, exactly, that's the message I get.

it is - I mentioned this earlier (first sentence above!)

The "editing window" that is, the Denemo Display, can have its color
set from Scheme - I forget the syntax, ask if you need it - while the
Print View is (IIRC) just the default i.e. theme-able.

LilyPond syntax highlighting?

The Gtk widget involved is GtkSourceView which has refers to a file
containing the syntax highlighting rules
do you get this warning
g_warning ("No syntax highlighting for LilyPond");
the code doing this stuff is in src/export/exportlilypond.c if that
helps.

I'll give it a try and report. Hi, I tried to modify various gtk3 .css files but didn't succeed. However, I noticed that in Abiword's menus the keyboard shortcuts are light grey and not dark blue as in Denemo. Otherwise the menu colours are exactly the same. Could it be that in Denemo the shortcut colour number is hardcoded? Talking about colours, is it possible to modify the background colour of both the editing and print view windows? Finally, I just noticed that in the version compiled by myself syntax highlighting doesn't work, while it works in the appimage downloaded from Denemo website. Any hint?
