string assigned to function is interpreted as colour

[nirazul]

I have the following color-function:

@function getColor($idx) {
    $color: pink;

    @if type-of($idx) == 'string' {
        $color: map-get($labels, $idx);
    }

    @return $color;
}

$labels: (
    'selection': rgba(0,0,0, 0.15),
    'blue': #0071b0,
    'red': #dc0c42,
    'background': #727d8e,
    'lines': #D2D2D7
);

When I upgraded to latest node-sass version, the function suddenly stopped working for the values blue and red because type-of($idx) returns 'color' for them:

background-color: getColor('label', 'blue');

Versions:
node-sass: 3.3.2, which means libsass: 3.2.5

A related issue is: #652
...but it's marked resolved.

This is fixed on master and will be the next version of LibSass.
