Color wheel not working

Not sure what I did that caused this but why does my 'Create' tab look different and no longer function? I can't see any of the swatches and the color selectors on the wheel are all gone except for one which is just stuck on grey/white (background color) off the color wheel. I can't even move/click/affect the color on the wheel at all. I can select the color mode presets (analogous, monochromatic, triad, etc.) but it still doesn't trigger anything else on the page. All other tabs work normally.
