There are many Color plugins for analyzing different types of color images. And once you have converted color into the values of a specific channel you should be able to threshold it the regular way.

Does anyone know if there is a plugin for ImageJ that will threshold an
image by color? If not, how does one segment a color image to identify
particular structures, in this case nuclei?
Thanks,
