Add ability to change background color(s) via API

Hey! I was told to post here with script ideas for you to do in your free time. I am commissioning a script now that will automatically add a grid to file names that include 16x16.

I was hoping to also automatically change the background colors located in Preferences > Background > Colors for every image that I open in Aseprite. This will allow me to easily see all spritesheet sprites without modification.

The script developer informed me that under the commands API there is no such ability. This would be extremely useful to I’m sure not just me and would be amazing if added to the API. Alternatively, simply allowing you to start or open any existing document with a defined background color would be amazing.
