Because GTK3 has several times changed its API during development of version 3 for getting and setting the color of widgets (Gadgets in PureBasic speek) and thus being a movable target, the PureBasic developers seem to have given up to adapt the SetColor commands.
But you may try the following example to change the backcolor of ButtonGadgets (which is derived from
this much more general color module from mk-soft and others). I have tested the examples successfully on Linux Mint 19.3 'Tricia' x64 with Cinnamon using GTK3 and PureBasic 5.73 x64.

If you include mk-soft's color module, the actual example will become much shorter:
Code: Select all
EnableExplicit
XIncludeFile "/path/to/color-module.PBI"
OpenWindow(0, 100, 140, 280, 140, "Set backcolor of ButtonGadget")
ButtonGadget(0, 80, 30, 100, 30, "Button 1")
GtkGadgetColor::GtkSetGadgetColor(0, #PB_Gadget_BackColor, #Yellow)
ButtonGadget(1, 80, 80, 100, 30, "Button 2")
GtkGadgetColor::GtkSetGadgetColor(1, #PB_Gadget_BackColor, #Red)
Repeat
Until WaitWindowEvent() = #PB_Event_CloseWindow
