Look! Took the time to actually put it in order. This one was fun. Red and white were winning and then black came roaring up the ranks with 12 films in the, you guessed it, 1970s. I also counted ‘Blacula’ so if you are a purist, please think of black only having 34.
Firsts!
White Eagle 1922
Black Oxen 1923
The Purple Highway 1923

For future reference, I use wikipedias list of films released which is probably incomplete. I also start in 1920.
Prince, breaking new grounds always and forever.
I never meant to cause you any sorrow
I never meant to cause you any pain
I only wanted one time to see you laughing
I only wanted to see you laughing in the purple rain
