Leather Types

I can definetly feel the difference in the different leather types but what is the difference between the following:
HOH Soft leather (new HOH Dual COre gloves) I think there was a brown modified trap model a few years ago that used this
HOH Pull Up Leather (the oxblood HOH)
HOH Oil Tanned
HOH (standard no oil)
I guess what I am looking for is are the different leathers based on the color they are using or the quality of the leather?
Any help would be great.
