Is there a viewable master legend that tracks all color-coded keywords for quick reference?

Hi. Newbie here… I have a novel with lots of visually color-coded keywords. Characters, themes, timelines, story icons, etc. I’ve used the easier-to-visually-track Labels on POV.

Because there are so many color-coded keywords, when I make them visible tabs on the corkboard cards it becomes very hard to remember what color is associated with what keyword.

So… I’d love to click a button and see that master list in the Inspector. Is that possible. Any work-arounds? Thanks you!
