Lab Color Adjustments

The Lab color tool allows adjustment of colors in Lab color space without affecting the L-channel of the image so that relatively color-free parts of the photo are not affected. Note that the blue color enhancement in the right panel has been accomplished without adding a tint to the comet nucleus or stars.

Below is an example of enhancement applied to M45. Adjustment settings used were R=0.7, B=1.1.
