Bearings dont "make black stuff".
And the color of the grease is really not an indicator of its condition.

Bearings, no, they won't turn the grease black or any other color.

HOWEVER, DIRT/DUST/BRAKE DUST/WATER can and does change the color of the grease.. Poor or worn out dust seals can allow all of the above to creep in to the bearings and grease.

Improperly set bearings can also cause overheating of the grease and can turn any grease black in a hurry.

Always best to check and repack your bearings periodically, fresh clean grease is always good and well worth the effort.

I do know that the OPs post was a joke, not so much for yours.. But thanks for the potential sarcasm.

I had a cheap Chinese bearing that had a ridge on the inner race from improper manufacturing and it turned the fresh red grease to gray in short order. No contamination from external sources, just the fine metal particles from the junk bearings.
