Wrong output of color() in cssnext playground

[Macxim]

In cssnext playground,
color( [ <color> ] [red( | green( | blue( | alpha( | a(] ['+'] [<number>] ) ) doesn't seem to render properly.
No problem with ['-'] though.

.class{
  background-color: color(#2B88E6); /* expected: rgb(43, 136, 230) */
  color: color(#2B88E6 red(+30)); /* expected: rgb(73, 136, 230) */
  border-top-color: color(#2B88E6 green(+100)); /* expected: rgb(43, 236, 230) */
  border-bottom-color: color(#2B88E6 blue(+20)); /* expected: rgb(43, 136, 250) */
}

will render in

.class{
  background-color: rgb(43, 136, 230); /* expected: rgb(43, 136, 230) */
  color: rgb(255, 136, 230); /* expected: rgb(73, 136, 230) */
  border-top-color: rgb(43, 255, 230); /* expected: rgb(43, 236, 230) */
  border-bottom-color: rgb(43, 136, 255); /* expected: rgb(43, 136, 250) */
}

I can't seem to reproduce this issue anywhere else.

playground is just outdated.
This bug should be related to something like this https://github.com/ianstormtaylor/css-color-function/blob/master/History.md#121---march-16-2015 (fixed)

caniuse-api wasn't fully compatible with browserify so playground was outdated + adjusted by hand in order to work for 1.0.0 release.

I have made a PR so we can bump playground and close this issue: Nyalab/caniuse-api#26

Alright, thanks for looking into it.
