ISSUE: Color pack schemes are not updating in the Customizer

If you have installed both One Color Pack and Two Color Pack, the two-color options will override the single and become your default. If you’d like to enable the One Color Pack settings, head to Plugins from your WordPress dashboard, and deactivate your Two Color Pack plugin. 

The code nerd explanation: because our Color Packs target specific titles, links, and areas of your site, when both plugins are activated, your code isn’t sure which color scheme takes priority, so as a default, it picks the two-color.
