What does your magic look like?

I've been pondering this for a while on how I want my magic to look and wish to know everyone's perspective on this. What does your magic look like in your world?

Elemental magic is pretty self-explanatory, but what about the more hard to define one's, the obscure and outlandish, or unique twists to existing concepts?

For me, colour is always a big factor in it. I try my best to give each magic type a different colour or combination of colours.
