Here's my second plug-in, "Average Color (HSL)". The original idea for this plugin is due to phrebh, who brought this up in the other thread. It's based on the observation that averaging the color of a selection might make more sense in a color space that better reflects human perception of color than sRGB does. I would have used CIELAB, but an average of valid sRGB colors in CIELAB space won't necessarily yield another valid sRGB color.
The following examples demonstrate how this effect differs from a comparable plugin that averages the RGB values directly, Average Color of Selection. I ran each effect on twelve different blocks of each image.

Many thanks to the following people for helping to make this plugin possible: Rick Brewster, Tom Jackson, BoltBait, Sepcot, phrebh, and MJW. As usual, install by copying the .dll to your effects directory. License (MIT) is included in the archive. Enjoy!
I'll be glad to release the source if anyone would like it, but the project is a little disorganized right now, so I'll have to clean it up first. Let me know...
