Weird grey/black plastic balls on my blue print?

My issue is that when I print with my blue PLA, I can see these small half-blue half-black balls on my prints, and I'm not sure what to do about these little things. Can you tell me what they are and how to make them not show up?
It sounds like you might have some of the PLA burning up in the nozzle and/or on the surface of the nozzle. This can sometimes be caused by over extrusion or impurities in the material burning up.
I have seen this a lot in Zortrax Z-ABS when using the colors Yellow, White, Blue, and Green. If I remember correctly it was just the color filler burning up at the temps they had set but this was a specific thing to Zortrax and their material.
What PLA are you running and how hot are we running on it?
