body{ color:lighten(unquote(map-get($colors, yellow)), 5); }

            ^

This is a valid SCSS code and should be compiled successfully. verified with http://sassmeister.com/

This is being compiled using my GULP setup, and this is the JSON configuration:

This is a problem with libsass, which I think has been fixed in the meantime (but there is no new release yet). I get this

DEPRECATION WARNING: Passing #FFDC00, a non-string value, to unquote()
will be an error in future versions of Sass.
        on line 2 of t.js
body {
  color: #ffe01a; }

Ruby Sass gives the same.

so what should I do now? I want to be to do such things.. how can one know if this has been fixed or not (on libsass) ? is there any ticket?

If you feel brave you can fetch the newest libsass from git and compile node-sass against it.

Fixed in https://github.com/sass/node-sass/pull/1214. Will be in v3.4.0.
