Blue, absolutely

Science is blue (dark blue, if given the option).

Math is red or black.

English is green.

Social studies is yellow.

Everything else goes in whatever is left.

The one I was always certain about is that biology should be green. Chlorophyll and the photosynthesis based on it are just so important for nearly all life forms that green is very much deserved by biology only.

Orange for me

Science was green

Also math was my favorite subject, and red is my favorite color, so math was red

Green = bio / blue = my language / red = math / black = french / black = english / yellow = german / orange = geography / purple = history / other stuff a folder with flowers / stars on it.

Those colors I used in my last year off high school.

I will drop death befor I use a pink one.

Which of the science subjects?

The amount of time I spent before clicking and seeing comments, to ensure no outside influence... Long. ND long. 🥁🥁🥁 Green.

Math is red, Language is yellow, History is orange, Science is blue OR green depending on the focus (physical science is blue, biology is green), Music is purple, though I was a band kid so I usually used the bigger music folders you got from the instrument shop. Art is whatever color science isn't because I'm not going to use the folder anyway and the sketchbook is always either a painting or brown.

I could also hear arguments for switching math and language.

Maths - Blue Physics - IDFK, red? Purple? Chemistry - A different Blue Biology - Green Geography - Orange... or Green again.

Blue of course.

You folks used folders?

The color pink does not exist.
