Badges need a basic set-up to be easily recognized as MPLIC badges and what "level" they are at.
Color can be used to change annotate the section it fulfills--Orange for Science, Green for Technology, Red for Engineering, Blue for Arts, Yellow for Math.
What level is the person at? The "stitching" along the outer edge of the badge can show what the person has done--
Level 1 / Read--Black
Level 2 / Visit--Silver
Level 3 / Participate --Gold
Level 4 / Review--Platinum / White
