It is not easy, @Elio that made the prototype in the other thread had to follow the guidelines for the branding so there are different reason of that prototype made in that way.
in few words the issues actually that the Reps logo has (as I can remember):
- In the guidelines wasn’t clear about if we can use our specific red and not the defined in the manual
- if we want to change the icon that we are using
I suggest to read https://mozilla.ninja/, as Council we stopped working on that because we had and have issue with more priority and until the guildelines wasn’t clear for us we preferred to work on something else.
