idea for kb refactor of Y.Color.Harmony

_getOffsetAndFinish.js

/**
Generates a series of colors from startColor at various offsets
@protected
@method _getOffsetAndFinish
@param {String} startColor     Start color
@param {Array} arrOffsets      Array of colors
@param {String} [to]        
@returns {Array}               Of offsetted and finished colors
**/
_getOffsetAndFinish: function (startColor, arrOffsets, to) {

    var ret = [],
        i = 0,
        c0 = Harmony._start(startColor),
        to = to || Color.findType(startColor);

    for (;i < arrOffsets.length; i = i + 1) {
        ret.push(Harmony.finish(Harmony.getOffset(c0, {h: arrOffset[i]})), to);
    }
    return ret;
}


// so something like getTriad becomes something like
// ie quite a lot smaller kb wise
getTriad: function (str, to) {
   return Harmony._getOffsetAndFinish(str, [0, TRIAD_OFFSET, -TRIAD_OFFSET], to);
}
