so the basic five dragons, taken from existing D&D will be:
- red: fire
- green: poison
- blue: lightning
- black: acid
- white: ice
and then:
- red + green = yellow: fire + poison = smoke
- green + blue = cyan: poison + lightning = ?
- blue + red = magenta: lightning + fire = plasma
- black + white = gray: acid + ice = ?
let me know if you have suggestions for the breath weapons of cyan and gray dragons
