The Brand.ai Sketch plugin enables you to share not only global colors, but also your text styles, layer styles and symbols with your team.
You simply add your palette to the cloud, and all team members who have the plugin can use the colors in their local documents.
If you make any changes to your elements, Brand.ai pushes the changes instantly to everyone who's using the plugin, so your team is guaranteed to use the most recent styles.
For more details, check out the blog series "How to share a design system in Sketch".
Disclosure: I am the Co-Founder and CEO of this plugin.
