well guess what else is yellow ?

That dad is correct. History is yellow
- Come to think of it, all of my history / social science folders were yellow.
  It weird how nature do that.
  
  I feel like the dad is describing exactly how I color tabbed my folders.
  Maybe there was some kind of standard back in the day?
- No cap, math is red as shit fam
  
  Red as shit. Science is blue and English is green, too, I'm pretty certain this is how I organized my school subjects

history is brown
- This I fully agree with
- Red gang. We can settle for brown red clay though.
- Or yellow if you don't have brown.
- yes, because most of german history is nazi history and nazis are brown
  (at least back then, now german nazis are blue)
  
  I find this comment to be Jastorf the Mark.

Automation is red, logistics is green. Factorio decided this years ago.
- DSP decided that automation was blue, logistics is red, and white is still white, lol.
- Wait I thought yellow was bad, red was better and blue was best
  
  yellow is pretty hard to make. low density structures and blue circuits completely fuck your copper lines unless you prepare

The rest of this is up for debate but science is absolutely green.
- Star Trek didn't think so. Their science uniforms are blue.
- Definitely blue
- The Research bubble in Civ is blue and that's really all I need to know I'm right.
- super green
- History is absolutely purple.

Where do you have only one "science" school subject? I always had physics, chemistry and biology separately.
- And biology is definetly green.
- Elementary school was like that for me. Just "Math, Reading, Science, Social Studies." I still don't know how geography fell under the umbrella of social studies.
  
  Probably because geography has had a huge impact on societies and cultures, if I had to guess
- Pretty sure they're talking about the colors of question categories in the board game Trivial Pursuit.
- Math or history didn't bother you? The last time you had a class called "Science" was probably the same as the last time you had a class called "Math" and a class called "History": elementary or junior high.
  They're being used as general subject terms...
  
  That's a very American point of view. I had multiple science classes (Physics, Biology, Chemistry) and a single Math and History class each. (I'm from Germany)
  The different math classes that I know of from the US (Trig, Calculus, etc.) are all just taught in Math class according to the school year you're in.
  
  I always had just one math class (the last one was "Math for physicists 3", in the third semester at university) and what would "history" be split into as a school subject?
- We had 'physical science' freshman year, then it split after that.

In my country, squared paper notebooks are usually green, lined red and blank blue. It’s been like that for decades. So math is green.
- Oh bože spomienky na strednú školu

Meanwhile, Coldplay:
"And it was all Yellow"

Starfleet is expanding its number of departments.
- It got a little out of hand with the original movies. Despite everyone wearing red jackets, their collars had colors based on their departments. There were seven in total at that time:
  Red = Trainee
  Light Green = Medical
  Dark Green = Security
  Yellow = Engineering
  Blue = Special Services
  Gray = Science
  White = Command

Green - Residential
Blue - Commercial
Yellow - Industrial

Math blue English yellow Science green History brown
- History is yellow/awesome.
  English is tan.
- Never identified with something more
- This is the way

Math is red, English is blue, History is Yellow, Science is green. I have spoken
- This is the way
- This is the way.

Meth is blue

Same dude calling Math blue and yellow
- Glad I’m not the only one that noticed

Green is science, yellow is history, blue is English, math is red
- Finally, some sanity!

I feel like this meme is having an aneurysm
- Same. From comment section I get people are talking about being school kids but like... Social studies is 3 ring binder, math is spiral notebook with perforations, English is library book and black and white composition notebook, science is a folder that gets replaced monthly after it rips... All loaded into a backpack along with like 5 textbooks wrapped in brown paper

I once heard that there is a theory that things written on yellow is more memorable. Which is why the default original color for legal pads, post-its, and highlighters is yellow.
So yellow should be what ever you need to memorize more. So it depends on your teacher and how much of the subject matter needs to be memorized. I'd say it should be history as there are a lot of dates and minute details, but I could also understand it being used for any subject that needs memorization like foreign languages, science, and even math.
Blue and green are both calming colors so those should either be reserved for that classes that give you the most stress or the classes that benefit the most from being calm, like creative writing or music.
Red is an exciting color, use it on what ever subject you are most confident i or interested in.
I guess I think the bearded guy (wait...it that a beard or just a long mustache?) Is using my system correctly.

You guys had coloured stuff?
- "you see, in the past we were so poor, we couldn't afford colors" -- this pearl of wisdom brought to you by your nan who had to walk uphill both ways to school

A trivial pursuit for truth
- Thank you. Everyone knows history is yellow and science is green, it's a trivial fact.

Are we playing Trivial Pursuit?

Math is red Science is green History is yellow Writing is blue (because leftovers)
- This person has it right

Two synesthetics walk into a bar…

Maths is red, English is blue

Math : Red
Science : Blue
Language Arts : Yellow
History : Green

If there’s two things I know in this world it’s that math is red and science is blue.

Math Green Science Blue History Yellow Writing Red
- Science is Red, you fool!
  English is blue. History is Orange/Yellow.
- Since transitioning to work, but still keeping a notebook, I use the following. Colours based entirely on what pencils/highlighters I had when I first started taking notes at work.
  
  Assigned work Blue Ad hoc Orange Errors Pink/Red Solutions Green Actualizing Yellow WTF Purple
  
  Purple is for joint operations.

English-Purple
Science-Blue
Social studies/history/civics-Green
Math-Red
Homework-Yellow (or one year I had a pinkie pie folder)

Green is maths and I will die on this hill

Green is biology, blue is physics or generic science.
History is purple
Literature and language are red or pink
Yellow is an objectively disgusting color which is chosen for the objectively worst subject: math.
- Magic is purple! * Throws chair *
- That's funny because everything is math. All the way down.

Math is definitely blue, science is definitely green. ELA was yellow, but history/social studies was purple.

History is green, dumbasses

Math is red, science is green or purple, writing / literature is blue or yellow, history is yellow or green.
- Agreed except Science is blue and Writing is Purple per Civ rules. Also, what the fuck are we talking about?

For me,
Math - red
Science - blue
History/geography - green
Language arts - yellow
Art - purple

What color does hat guy think Math is?

Black and yellow, black and yellow, black and yellow

Green is history, blue is science
- You've got it ass-backwards, m8! throws chair

Science is green. History is yellow/orange. The rest are whatever.

If your shit is yellow you should see a doctor.
- Or a teacher

And soylent is green!

Biology is green, Chemistry is blue. Math is purple. History is brown and/or orange. Writing is red.
- Math is blue, no discussion 😇
  
  🤐

Science is Blue, Math is Yellow, English is Green, History is Red.
- Only correct opinion

Is this just based on what color your earliest textbooks were?
- Folders for each class

Hmm, chemistry red, biology green, physics blue. The rest we'll need to think about. I can probably accept yellow or orange for maths.

Math is gray
Science is blue
Writing is black
History is brown
- Who tf had gray, brown, and black?
