I love the functionality of the new style guide, and I'm not sure if it in the future will replace the brand colors in the "colors and logo" settings on the account.
If not, then I would prefer that the style guide pulls the brand colors and make that the default setting and then you can always add new style guides.
As for now, the brand colors doesn't even show i the color picker in the style guide - which I find somewhat strange as the color picker normally pulls the brand colors as well... Maybe it's just a bug - but if not then I would really like to get it fixed.
Thanks
