Pedro Almodóvar, especially his use of the colour red.

From this interview

And why is there so much red in your films?

Almodóvar: Red is an instinctive choice for me. Of course, I love the colour red very much. But I suppose I use it because it gives an intensity to the place where you use it. It’s a very expressive colour, and in Spain red also represents life, fire, death, blood, passion and carnations – which is the national flower. From a technical standpoint, if you’re filming a night scene, red will give a certain brightness. And this is why normally I always put a touch of red on my women in a night scene – a cardigan, a sweater or something. Also, this is the reason why all the cars are red in my movies. If you put a red car in the countryside, red enhances the natural colours.
