Green, I just feel since magic is often connected with life-force (or death-force), it would be green.

Purple, because purple technically does not exist.

Red. Cause I just like the color and it's seems the most magical to me lol

Cool \('-')/

Depending on your personal magic (Vinita),(Mana), (life-force)

Or rather what type of magic you're using

Even what you draw power from can influence your magic's characteristics and essence

There's a give and take balance whether it's (white magic) (grey magic) (black magic)

in my opinion the spell does not have a defined color each type has a different color, but even in some of the same type the color is different, but this is usually related to the effects of the spell

Magic is colorless in that magic is all colors.

Gold or Purple

Purple

I do think that violet is the true color of magic!
