Add color previews for Color labels

[Ivan Zayats]

Add color previews next to the text names, please.

It would make the workflow easier when we don't need to remember what color name we've used for this or that group of clips. Some colors are pretty similar, some names are too exotic (though they're customizable, but anyway).

I am locking this idea, as it is a duplicate of an idea that will soon - by the end of January - be migrated to this forum from the old User Voice forum. Once the migration is complete, I encourage you to add your voice to the existing idea related to your suggestion. 

Thanks,

Fergus
