Among the many color correction tools in After Effects is Synthetic Aperture’s Color Finesse, which comes free with AE. Many do not like the modal interface that takes over the screen but Color Finesse does fill gaps in Adobe's tools, and a bit differently than Colorista and Magic Bullet.
Chris & Trish Meyer posted On Artbeats.com: Intro to Color Finesse about an article that tours the Color Finesse interface, and then walks through a sample correction using footage archived with the article.
Steve Hullfish, whose first book on color correction revolved around Color Finesse, also included Color Finesse in his video tutorial series on color correction recently on PVC. In Fix it in Color Finesse - or adapt it to Color, Steve shows how to balance and fix a dark image. An older overview video by Total Training is available through Toolfarm.
