The Norton wheels are good. some like them better than the white wheels. They do last longer and don't groove as bad from what I hear. I purchased one when they were on sale but my white ones are holding up really well and it might be a year or more before I need to change it.
Wheels are colored by the manufacturer to show what they are but they may vary by company. The Blue, pink and white wheels are all good wheels for sharpening High Speed Steel. They each vary slightly simply because that company has decided what's what this particular wheel needs to sell to their customers.
The most important thing is how you use the wheel. True it up, keep it running true, clean it periodically, use light pressure to sharpen your tools and any of the 3 mentioned above will give you years of good service.
