Tinted glass and window

Hello to all: I am building a panel and in the front windshield and have a sunvisor. I want to make this sunvisor see through. In other words I want this visor to have a green tint somthing like sunglasses so it would be possible to see through it. How do you make a color tint to the windshild? I know that if you use 100percent black you get a clear window. But I want to have a tint. Any help welcome
