I am on my road to the second city of the game, and enter a figth with a skeleton that has the moon star sign. The game says that sun(red)>moon(green)>star(blue)>sun, but both when my sun and star familiars deal damage through the attack comand it is displayed with blue numbers(less effective), and when he hits either familier, the numbers are red(very effective, I think). Can someone please explain what's up?

Also i am sorry for any grammatical errors
