Excellent! Rated 5 out of 5 stars

I love this! It saves my eyes and makes things so much fun!

There is one little problem, though. If I hold ctrl and click I can make a division bar under the Property Group button. I love this; however, I cannot make the division line go away or move it to a new location. I want to be able to move the line up to a different spot.

Other than that, it does not color the Google search results. :(

A cool thing I think would be nice is if I could exclude certain colors. I wanted to do an infrared vision effect, which turned out cool for the most part, but infrared vision is white, yellow, orange, red, violet, purple, blue, black ___ It's hard to exclude green and cyan, and pink...

This review is for a previous version of the add-on (5.4). 

1) You may use ctrl-click again on a property to remove the division above it. Dragging of lines or properties is not implemented, but would be nice indeed. I may add drag-and-drop capabilities in a later version.

2) As for Google, it renews the page in a way which is not recognized by Colorific, such that search results are not colorized from the second page on. I am looking for a general fix for this kind of problem. For now, you may double-click the toolbar button to re-apply the colorization manually.

3) The order of the colors is simply fixed by the HSL transform, although it could easily be defined otherwise. Methods to define arbitrary curves in color spaces do exist, and I might one day add those to Colorific.
