I figured users may not feel as apprehensive about the dark scheme, if I could make custom toolbutton images change between black and white like the default AutoCAD buttons do. For a good example, see the Text button image on the Home tab. The A is white in dark scheme and black in light scheme.
I've been unable to replicate this behavior on custom buttons. I haven't found a color that will switch. In fact, even when I start with a default button and save it to a new name (without actually changing anything), it becomes static and will no longer switch.
Anyone know if it's possible to do this?
You need to create a resource file for both the light and dark themes:
