The ideal logo may use color, but should also look good in monochrome (for wide applicability, e.g., T-shirts, mugs, etc).
Our internal branding has frequently made use of dragons (our "spirit animal"). Hoping to have some reference to money (e.g., gold, dollar bills) since our team earns money for the company.
Some ideas we had:
* A cartoon dragon breathing dollar bills with "Ads Frontend SRE" underneath.
* Dragon perched on a hoard of gold (protecting company earnings).
This logo should have "Ads Frontend SRE" included, not just "SRE".
"SRE" stands for Site Reliability Engineering. Everyone within the company already knows what it stands for, so use of the acronym is strongly preferred.
