I am in the process of making a web page and I have a "thanks to" section which shows the logotypes of different organizations. The customer wants these logos to be monochromatic; as in white background and dark gray logos (not shaded). However, one of these organizations is an embassy and they use the national flag as their logo. The flag in question is Taiwan's, but It seems that we are going to need to incorporate some other flags as well. So, how would you design a monochromatic flag in this case? Thank you for your time.
