颜色插件仅比 UI 库便宜 4kb。当然你会想要使用插件的decent version 而不是some buggy old thing，它不能处理Safari，并且在转换太快时会崩溃。由于未提供缩小版本，您可能想测试各种压缩器和make your own 最小版本。在这种情况下，YUI 获得了最好的压缩，只需要 2317 个字节，而且因为它很小 - 这里是：
(function (d) {
d.each(["backgroundColor", "borderBottomColor", "borderLeftColor", "borderRightColor", "borderTopColor", "color", "outlineColor"], function (f, e) {
d.fx.step[e] = function (g) {
if (!g.colorInit) {
g.start = c(g.elem, e);
g.end = b(g.end);
g.colorInit = true
}
g.elem.style[e] = "rgb(" + [Math.max(Math.min(parseInt((g.pos * (g.end[0] - g.start[0])) + g.start[0]), 255), 0), Math.max(Math.min(parseInt((g.pos * (g.end[1] - g.start[1])) + g.start[1]), 255), 0), Math.max(Math.min(parseInt((g.pos * (g.end[2] - g.start[2])) + g.start[2]), 255), 0)].join(",") + ")"
}
});
