It seems we have the same issue. Updated to 2.7.0.beta5 (6c57f6f49d) and the color scheme was no longer applied in our theme component.
We use:
#meta-links {
background-color: $header_background;
}
but the background color was #fff instead of the color defined in the color scheme.
I tried:
- re-assigning the color scheme to the theme
- copying the color scheme and assigning the copy to the theme
- re-assigning the theme component to the theme
but it did not seem to work. The current workaround is to manually set the color in the CSS.
