In Frappe v15 colors have changed from blue to black. How can I change the primary colors, all btn colors, and the secondary for the whole desk? I was trying to look around if there is an override for CSS just like js but no luck.
Nothing built in that can do that.
There are a few new themes popping up in GitHub, with multiple theme options. Maybe you could install one of these and using the v14 theme to replace it.
Like the Sundae themes and switcher
Thank you, but this will not work in my case.
You could create a custom app and write your own css for changing the colours and such of particular elements.
Then use hooks to override the default css with your custom css for the desk.
