Error compiling $color is not a color

[mrelliot69]

I'm trying to compile my files ( using bootstrap 5.0.2) and allways get this error
"Error compiling SASS -> $color: #3d78e3 is not a color.: assets//scss/admin\components/_ribbons.scss on line 153

The error line is this one:
border-color: darken(($value), 10%) transparent transparent;

from what i checked this seems to be caused by the bootstrap !default on the theme colors, any ideia how to bypass this error without messing on the bootstrap core file?

$primary: $blue !default; $secondary: $gray-600 !default; $success: $green !default; $info: $cyan !default; $warning: $yellow !default; $danger: $red !default; $light: $gray-100 !default; $dark: $gray-900 !default;

You need to define the color variables, it looks like those aren't defined in your scss files or variables.

I think this issue is similar to #504 where the extra parentheses around your $value variable gets parsed (wrongly) as a list containing a single value. Using darken($value, 10%) should work.
