Color is not set if label already exists in a different color

[GMZwinge]

If configured label already exists in a different color from the one configured, the color of the label is not updated. One must edit the list of labels and delete the label in the different color for the label to be recreated with the configured color. Also, as a side note, color such as Red1 or red don't seem to work. The hex color such as ff0000 or FF0000 must be used to work.

That's a good spot. Updating colours can be done.

Unfortunately, colours have to be hexadecimal. Octokit says:

The color must be a valid hexadecimal color code.
