I like the idea of black and white magic but need help

I like the idea of black and white magic because its something tieing to our real world as ppl were accessed of doing it etc. BUT i cant make it work in any system i try. it either becomes the shallow (good vs evil, light vs dark) situation that i hate because i prefer magic as a wonder or tool. however i cant use it as overall catagories because it limits the system greatly due to defininiton for example is conjuration spells black magic or white magic ? u can argue neither because its just summoniing and some argue its both because its about what u summon lke angel or demon or what the summon is summoned for AND THAT becomes the light vs dark problem.

so help iif u can because i like the idea of using irl magic as inspiration but i think im forcing it at this point if this doesnt work i have a basic element system i can trry.
