Hi, I have customised a colour scheme in MP, but my new scheme doesn’t work well with the button colours: 
Is there a way to modify the images without re-compiling?
Where do they live in the install directory?
TIA
You can change the icons, by placing replacement images into the install directory.
Size of each icon is 52x45 pixel. You can have two set, one for light themes and one for dark themes with light_ and dark_ prefixes in the names.

Thanks!! What about the main Ardupilot logo? What’s that called - there’s no obvious one in the resources directory.
For simple theming changes the logo must stay.
Rebranding however is a different story.
