plugin_languages_colors not working properly for go lang

[ilanRosenbaum]

I am using plugin_languages_colors: github and have tried plugin_languages_colors: github, go:blue and in both cases go lang is white. Given go has a color in the github colors I don't know why it doesn't work with color github nor do I understand why I can't manually set it. I'm probably just doing something wrong but I'm not sure what. For repro see my profile repo: https://github.com/ilanRosenbaum/ilanRosenbaum
