Supply a flat array of colors

[btopro]

Nested object / array is great for finding stuff, seems like it would also be a useful short hand to provide a transformation of these values into a flat Array.
something like...

let hex = Polymer.SimpleColorsUtility.instance.hexCodes;
                let colors = [];
                for (var i in hex) {
                  for (var j in hex) {
                    colors.push(hex[i][j]);
                  }
                }

This way you could call 1 function / value and get a (flat) list of valid colors for selection or testing against.
