I need help from those of you who were blessed with normal color vision.
I'm trying to identify these newly acquired postage dues.

The primary color used for this design was brown for the 1879 issue, red brown for the 1884, and bright claret for the 1891.
I think the 2c is the brown Scott J2 but I'm at a loss to call the other two.
Any help you can provide will be appreciated!
