>>714596352You're not obligated to pick RBG, but RGB is a lot better to look at than pic related, health was always going to be red, what's a nice contrasting color, blue!
What's a nice additional color? Green!
But magic didn't have to be blue, it could have been green and vice versa. Blue "feels" slower as a colour, a lot of cartoon characters are depicted as blue as a result, so picking it for magic makes sense in that regard. A lot of magic is associated with the night so that works double.
Health is red because that's blood, but green could work too, as a simple green=good, a lot of game use green for health too (with damage being red).
But stamina as green doesn't have much going for it. I liked the spinach post. Maybe green open field? That feels very esoteric.
