I wonder if the "Gold" titled ColorItem within "Yellow" ColorPalette above should be pulled down into being paired with this one now that it's here?

Edit:
Or if this should be lumped into the Yellow section instead of having Gold at all.

Got rid of the Gold section and moved the gold uswds color under Yellow after checking with Jessica.

Approving, but probably should circle up with Jessica to square away the comment on Yellow/Gold primitive section prior to merging.
