// We define a set of six board colors that we took from the FlatUI palette.
// http://flatuicolors.com
//
// XXX Centralizing all these properties in a single file just because their
// value is derived from the same color, doesn't make any sense. We should
// create a mixin/macro that would generate 6 versions of a given property and
// dispatch this list in the other stylus files.
