Bombshells: Lucille Ball as a Blonde? As a Brunette?

I love being a brunette. I love having dark hair. But I never feel that I can change hair color that easily or drastically. Models and actresses seem to be able to change on a whim and look great doing it! I recently found these amazing photos, on Pinterest, of Lucille Ball looking gorgeous as a 1930's blonde model, a 1940's Femme Fatale, and as the adorable 1950's red head we love! 

Which look is your favorite? Which hair color would you love to have? And wouldn't it be great to sport a new hair color every decade?
