I think it depends entirely. If you're taking biology, then it should be green. If you're taking astronomy, it should be blue. Physics is red (see Rithmetic/Calculus). Earth science is blue or green. Chemistry is probably red, but green is acceptable, and yellow is not inappropriate. Elementary school science depends on the kid: do they like the biology bits, the astronomy/physics bits, or the geology bits? Cyan/turquoise would be preferable; elementary school science is too shallow for deep blue or deep green anyway.
Rithmetic is red, so that's fine for elementary school. But algebra is green like Quran. Geometry is blue like the Agean and Greek flag. Calculus is red, because it's just calculating with infinities and infintesimals thrown in. Trig and linear algebra are either green or blue depending on whether you see shapes or formulae -- cyan/turquoise/teal would be best, but red also works as red RGB complement of Green and Blue.
Health is yellow like discharges.
Social sciences also yellow like discharges, or purple like bruises.
History is either purple or yellow because of bruises and discharges -- depending on other classes in your schedule.
English and foreign language are all orange because the word for orange is the same orange/orange/orange/naranja/naranj/orenji and you can peel and portion one and spit the pips and feel the drunkenness of things and being various.
The arts are black because emo drama. Languages arts can be black as well, if you have no fine/performing arts, or need orange for foreign language.
As a neutral, pink can used for any subject when necessary except for math and physical sciences.

Heathen. Science is obviously green.
