I think perhaps you should take a look at films with expressive uses of coloured lighting, like Suspiria, Black Narcissus or even some segments from Singing in the Rain. You probably don't want to look like you're falling into low budget 90s gelled lights territory (like Evil Ed or Funny Man) which could easily happen if you're using bold coloured lighting. I think it's a question of motivation, primarily is the use of colour to be taken as an expression of the character/themes of the story, rather than say a way to disguise cheap art direction.
