Color Picker Enhancements: Palette and Kelvin support

First-time poster, here.

While I'm not the first person to propose color picker changes in this forum, I do feel that -- while the current Blender color picker is adequate -- a couple of additional features would increase functionality and workflows, and wouldn't be too difficult to add. Might be a good consideration for Blender 2.8xxx

I would like to see the following additions:

• a set of static swatches for primary colors, secondary colors, and common grayscale values.
• another palette of dynamic swatches that update to reflect colors chosen during a given Blender session, similar to Maya's color picker swatches. This palette can be locked, imported, exported and cleared, and would support Adobe's ASE format for sharing palettes and swatch collections.
• support for entering blackbody color temperature values in degrees Kelvin. This would be similar to the "Hex" option in that the UI would switch to a single text field input, in this case for temperatures instead of hexidecimal values.

I had hoped to embed my mockup, but am new to this forum and don't know how. I've included a link to my mockup below, and will add the mockup as a custom thumbnail to see if that makes it show up in the post.

Thanks for reading. Cheers!
