In a release mail I received contained this information:
Admins can reinforce a sense of connection to the company with custom branding, making Guru feel more like your organization. Your custom colors and logo will appear across pages in the Guru web app, creating a sense of continuity across your company’s knowledge.
I can’t find where I can define “custom colors”. Where is this? I assume it is not referring to color option of a collection.
Hi 
Admins have the capability to request custom colors, and it looks like you’re an admin on your account. Here’s the Help Center article with more information: https://help.getguru.com/en/articles/6659170-customize-your-guru-team-colors
If you need more help with this feature, you can contact Guru Support by using the Help menu in the Guru app. Hope this helps!
