What the Auth0 Logo Colors Mean?

The Auth0 logo colors keep it separate from its owner, which is the interesting part. Okta bought the company in 2021 and kept the orange rather than repainting it blue, because the two sell to different buyers: Okta to IT departments, Auth0 to developers. The mark is a shield built from the digits of the name. Orange in a category of blues is the same move Cloudflare made, and it works for the same reason.
