As for colors, I'm not so sure. Many of them few designers would choose for reasons such as lack of alternate color with enough contrast plus long term use eye strain. I might reduce the number, perhaps to only those pleasing for long periods so they'd be quicker to access and more easily discoverable, reorder so similar colors are together, for example if a gray chosen is too light, select next, if too dark, previous, and some settings icon as the last swatch to add custom colors to appease those that want it.
