Q. What should a good spark look like on a spark plug?
A normal spark plug will have brown or grayish-tan deposits on the side electrode. Everything is just fine with your spark plug; you can reinstall the spark plug.
Q. Why is spark blue?
The short answer is that sparks are blue because of the colors given off from nitrogen and oxygen when they are excited. Essentially, light goes in, but doesn’t come out (like thunder dome). When light goes in, it reflects off the surface but some of it gets absorbed. Each time it reflects, some gets absorbed.
Q. Should I be worried if I see a very brief orange spark when I plug something into an electrical outlet?

Orange sparks should be taken seriously, as the Electrical Safety Foundation International reports that 51,000 electrical fires happen every single year.
Q. Why do my outlets spark when I plug something in?
When something is plugged in, or turned on, some of that very fast, hot electricity transfers from the outlet into the appliance, light, computer or whatever.
