Erpnext v15 custom theme

[pmjd]

Here’s a collection of themes, which you can customise the css on to suit your needs

Desk color scheme

I think the “usual” way is to create a custom app, modify the css in that, and it overwrites the standard desk theme. There are a few themes available on Github, one also has several options, which might be worth a look at modifying to make the theme you need. Has a slight issue with the gray text not being contrasted well enough to the black, for my eyes anyway. Very colourful and multiple schemes available. Tasteful dark pink, light theme
