Do what I do, and play around with the Color Correction effects. I always try to recreate the look of old, 35mm, technicolor film for my work, and I found that going into Color Correction and increasing the Brightness and Contrast, as well as increasing the Saturation under Fast Color Corrector, and adding just a hint of noise (not to mention rendering and exporting at 24 fps instead of 29.97), I find that I can get passable results: not exactly perfect, but close enough for jazz.
