MDL defines many RGB values as a string, so $my-color: rgba($input-text-error-color, 0.9); will result in an error: "Argument '$color' of 'rgba($color, $amount)' must be a color"

What we could do instead:

• Strip "rgb" or "rgba", "(", ")" and spaces from MDL SASS variable, e.g.
  $input-text-error-color: unquote("rgb ( 213, 0,0)") => "213,0,0"
  
• Split the comma separated string into a number list
  "213,0,0" => [213, 0, 0]
  
• Then feed the numbers into the wanted SASS function, e.g:

Polymer 1.0 : Custom elements

Simplest possible workflow

Minimal steps required to create a custom elemenet in Polymer 1.0, without any aid from tools like Yeoman and Gulp.

I have used the Quick tour of Polymer as a reference.

Prerequisites

• Install Node.
