Hi – the skin color option is not implemented in squash since we focused on single skin in this theme unlike other themes of ours. But making changes to default color is not too difficult either since most color scheme/skin specific styles are put into a single small css file called default.css
located in /css/skins/
folder. If you open that file, you can see a single color repeating.
You can copy the contents of this file to custom/custom.css
file and make a change to the single color used there to one of your choice. Pls have a look at that file and let me know if you need further help. Thanks.
