Colored Headlight Bulbs?

I want to change my head light colors. i want my high beams to green so i would need a green bulb that fits and i would like my low beams to be either stock or white. probably stock. but i would also like to have my turn signals change on my headlights, which means i would need green instead of my stock amber. does anyone know where i can find anything that would fit universally for colored headlight bulbs? i would greatly appreciate it. thanks.
