I’m trying to a group logo for my PMC/ro-mil based on our flag. I’m pretty satisfied with what the flag, however, in my opinion, the logo seems too similar to the U.S.’ Corporal rank symbol. (Double chevron)
I don’t really do logo design, but these are 5 steps of creating a good flag, which can be used for logos:
1: Keep it simple
2: Use 2-3 Basic Colors
3: No Lettering or Numbers
4: Use Meaningful Symbolism
5: Be Distinctive Or Be Related
