Issue Summary

Filtering a board by label color does not reflect the color in the browser’s URL (?filter=label:color)

Steps to Reproduce

1. Create a board with cards
2. Assign cards to unnamed labels e.g. one card with a yellow label, another card with a green label etc
3. On the upper right, click the Filters dropdown to filter cards by a label color
4. Select a label color, e.g. yellow
5. Observe the browser’s URL when choosing another label color
6. Try filtering with more than one label color
7. Try changing the url manually to another color

Expected Results

The browser’s URL should reflect the color being filtered for unnamed labels

Actual Results

Filter label defaults to any unnamed label color that isn’t being used yet in any cards e.g. shows https://trello.com/b/abcdefg/board-name?filter=label:blue in the URL if selecting a yellow label in the user interface

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available
