My personal belief is that the old Slack logo gave us information about what company does. The new Slack completely removes that feature. However, I did like the usage of the simple colors and shapes. My rebrand brings a bit of the functional aspect of the old branding, and the simplicity in the design of the new logo.
Enjoy. Any feedback would be appreciated!Demo: https://mrcool4000.github.io/slack-rebrand/ Source: https://github.com/mrcool4000/slack-rebrand/
