You must have hugo installed.
hugo server -Devcc is always written in lowercase, as you see in our logo. Please don't(!) do EVCC.
evcc logos, icons and vector files can be found in /artwork. Screenshots of the UI are located in /static/img/screenshots. Feel free to use them if you create content about evcc or build software/integrations in the evcc ecosystem.
The UI uses variations of these colors. The source of truth is the app.css.
