Depends on the science? Who has only sciences and not physics (orange), biology (green) and chemistry (yellow) separated? But mine were also out of hard paper and not plastic..

Blue for sciences... ah yes, the Star Trek system.

Blue is math, orange is chemistry, green is biology. My physics folder was always light blue but that's not in there apparently and then red is for your mother tongue language subject.

Of course everyone is different but naturally my colors are right so everyone else must be wrong.

• Red for Automation
• Green for Logistics
• Teal for Military
• Light Blue for Chemical
• Purple for Production
• Yellow for Utility
• and white for Space, of course.

Green because Trivial Pursuit says so

Green

Science: Green

Math: Red

Literature: Blue

History: Yellow

Red - English

Orange - Social Studies/History

Purple - Math

Science - Blue, but green fits too

Depends on where science lands on my schedule. I'd sort the folders in rainbow order and match that to the order of my schedule.

Blue.

Orange is clearly science
