the literal Enchantment school and the literal Enchantment card type are completely unrelated. Green Cannot effect the mind like Red and Blue. In fact Green is like modern Neuroscience where it cant differentiate where a Mind begins and an organic CPU ends.
Enchantments are Ongoing spells in MTG. in DnD Enchantments are Mind Affecting spells.
Enchantress is Not green in current color pie nad hasnt been for 4 years.
Anthems do not have a representation in 5E and do not represent actual magical effects
Magic the gathering has a mountain of rules tied to mechanical reasoning in terms of effects that are actual magic in terms of what each color does, and the fluff can sometimes be utterly useless, such as Impulse.
If its manipulating the mind, Emotional control is red, Thought control is Blue, Hostility in usage adds black, attempting to undo hostility or protect adds white.

Conjuration depends on the creatures being summoned. Fey will be Sultai, Angels make it White, Devils black, Demons Red, and many other combinations im not going over just because of what is summoned.
Foresight and Intense time manipulation is blue, while minor time dilation effects, such as haste and expedious retreat, are the territory of red.
Interacting with Good and evil is white and black.
Wish, while mechanically on 10? cards split between all colors, is actually a weird scenario. The effects of Wish can be any color, the very ACT of wishing is Red, assuming its the actual "Last minute, desperate pleading for intervention beyond reason and being rewarded".
