From what I recall....
Green's were their least desirable, lowest performing pads. Red's were/are their intermediate offering, & Yellow's were their highest product offering & designed for track use primarily.
I went straight for the Yellow's before going full tilt on the Wilwood's all the way around.
I liked the Yellow's & they served me well. Not as much brake dust as feared either.
No matter which pad you decide upon, be sure to follow the breaking in / bedding procedures they recommend.
