Color field: native picker

I got the following feedback from a client:

The color picker is a bit “fiddly” :-) Is there a way to make the field significantly larger or even sample from the screen like in PS (Photoshop)?

Which reminds me of input[type=”color”]. That should be wildly supported by now, right? I would love to have the option to enable it. The native color picker (at least on Mac) can be resized and it can pick colors.
