URL-encode color SASS function / convert color to hex SASS function

library.scss

//does not work with colors containing alpha
@function encodecolor($string) {
	@if type-of($string) == 'color' {
        $hex: str-slice(ie-hex-str($string), 4);
        $string:unquote("#{$hex}");
    }
    $string: '%23' + $string;
	@return $string;
}

Thanks so much! I also had the same problem as jacobdubail.

Thanks, that's very useful 👍

does not work with colors containing alpha

Here's a little improvement, accounting just for that — makes it more convenient to use variables:

@function encodecolor($string) {
  @if type-of($string) == 'color' and str-index(#{$string}, '#') == 1 {
    $hex: str-slice(ie-hex-str($string), 4);
    $string: unquote('#{$hex}');

    @return '%23' + $string;
  }

  @return $string;
}

// TESTS
$test-key-color: cyan;
$test-hex-color: #1ef;
$test-hsl-color: hsl(184, 100%, 53%);
$test-rgb-color:  #11eeff;
$test-rgba-color: rgba(17, 238, 255, 0.69);

@debug encodecolor($test-key-color);  // cyan
@debug encodecolor($test-hex-color);  // %2311EEFF
@debug encodecolor($test-hsl-color);  // %230FEFFF
@debug encodecolor($test-rgb-color);  // %2311EEFF
@debug encodecolor($test-rgba-color);  // rgba(17, 238, 255, 0.69)
