Load color swatches?

I'm not sure what you're doing exactly but I keep color palettes in Creative Cloud Libraries.

Go to Window > CC Libraries.

Click on a color swatch to save hex value to Clipboard.

Paste color values into your site's stylesheet (CSS file) with Ctrl + V.  See screenshot.

Save document (Ctrl + S). 

If you wish to add paint chips to the color picker panel, move your cursor over code color value, right-click and select Quick Edit.

Paste value in the color field and hit the PLUS (+) sign.  When you're done, save document.

That said, I rarely need the color picker.  For me, working directly with code is much faster & more precise than panels.

So, I created a new HTML page, added an image of my color palette to the page, and repeatedly clicked the eye-dropper, clicked a color from the image, then clicked the + button to add it to the palette in CSS designer, over and over again to compose a palette of our 16 brand colors... 

And of course, you simply can't to that, you have to add a class to the image, add a style source, then add a selector to the class first, all in order to even access the CSS designer to perform that mind-numbing, tedious and completely uneccesary operation to simply get a color palette in the workspace...

Once that was completed, I saved my Workspace to ensure that the color palette would be saved... only to have DW crash when editing HTML on the actual page I was previously working on and I bet you already guessed that yes, my color palette vaporized into nothingness whan I re-opened DW. Not part of the workspace?

Really?

As is often the case with using Adobe products, user experiences like these are unacceptible, and I wonder if Adobe can explain why their customers can expect to keep paying a subscription every month for this treatment?
