Setting Up Coloured Weather Icons

Ok, I am finally getting my head around themes, but I have a question about the weather icons.

As seen in this theme: https://github.com/liri/lovelace-themes/blob/master/README.md
The weather card has colourful icons. EG, sun is yellow and cloud is blue.

There is no mention of it anywhere, and after activating the theme, my icons are all the default colour.

Please just point me in the direction of setting this up. Any help is appreciated.

Well, I know why I didn’t get any replies… It just isn’t as easy as I thought.

I did find the answer though: https://github.com/iammexx/home-assistant-config/tree/master/ui/darksky

Turns out, my searches on google were not giving me what I was after because I was using beginner terminology. EG: How do I change the Weather Icon Colours on Home Assistant.

I was going to delete this post, but I think if google indexes it, it will help others find the solution, as complex as it might be.
