Free to view or download, our Guiding Principles of Flag Design are full of best-practice advice for every flag designer.
Covering terminology, basics, colour, structure, devices and symbolism, the guide suggests elements that tend to work well, or do not.
It does not cover aesthetic appeal, however, and there are plenty of successful rule-breakers.
The flag of South Africa and the Pride Flag, for example, both use multiple colours to great effect.
So enjoy your designing, have confidence in your flag, and do whatever you feel works best.
