UI-Minimalist How to tweak theme (colors)?

I’ve got an Android phone in dark mode, and finally building out my ui-minimalist theme. I am flabbergasted how awful the UI looks:

So I did some research and discovered those colors are buried in this .yaml file:


So the question is, what tool can I use to figure out what all the gobbledygook r g b values are in that file so I can adjust them on the fly rather than changing one digit, then reload the front end, then try to change another digit… it would take a lifetime to figure out - ?

This should do it for you

Thank you @NathanCu, I could easily do that in windows with a variety of tools as well, but 1. what about colors like #BBBBBB, and 2. that is almost as painful since I have to keep trying to refresh after every change - but also it seems like it doesn’t matter what a lot of those colors are since everything is already coming out as black anyway, so alot of changes to that file would make zero difference!

Would you or anyone have a file that has already been altered to fix running into the same issue?

Not sure if you figured this out already, but…

The reason there is a lack of colors in your first screenshot is because you need to go in to your app settings and in the Theme-section you need to select one of the minimalist themes available.

Unfortunately the changes made to the minimalist-desktop.yaml revert to stock when rebooting. So the colors don’t stick. Anyone knows?
