i was a little quick on my answer here.
So we set the css classes for the svg but as far as i see there is no way to tell adaxes to use a new color for dark mode.
As i mentioned our logo is dark green and on black background it's quite hard to see.
If i set the color to css class "u-icon-color-accent-1 " it will use this color for both modes. Which is also dark green in our case.
So, is there a way to specify which css class to use on dark mode?
For example if light mode is enabled use dark green logo if dark mode enabled use white logo.
