Rated 5 out of 5 stars

This is working for me in TB 45.2.0 on Windows 10 64-bit. It appears to be incompatible with the Remove Duplicates extension, however. With that extension installed, selecting a color from the picker would not actually change the color of a folder and "com.fisheater is undefined" would appear in the error console. Color Folders began working immediately after removing Remove Duplicates and restarting.
