I recall that Grande Dog on A.S. commented that the 'pink' Oregon wheels were slightly coarser than the 'pink' Molemab wheels from Bailey's. So color may not translate exactly between brands. And when I worked at 3M, the sandpaper guys would tell me that there were lots of different grades of aluminum oxide, so there may be additional differences there as well.
When I was testing the cheap, Harbor Freight grinders, swapping to a coarse, pink wheel made a HUGE difference over the fine, red/brown wheels they came with.
I still prefer a well dressed 'pink' wheel over the $100 CBN wheels I tried.
I had a chance to try a Tecomec 'brown' grinding wheel, but did not find it much different than their 'pink' wheel. Except that the brown wheel seemed to generate more dust and was more likely to overheat the cutters if not careful.
Also spent some time exploring resinoid wheels:
