Driving down the road yesterday they were repairing some electrical lines and I guess one of them sparked and it left a trail of blue sparks on the ground. But when I hook up a battery and short it with a wire sparks appear an orangish-yellow color.
Anyone know why?

Electricity has no colour. The plasma created by the electric field releases light when it reforms into normal atoms. The colour changes depending on the plasma too. If you do welding and hit a copper object e.g. wiring, you would see the arc to be greenish.
When atoms split into the nucleus and electrons they require a specific amount of energy and when recombined they shoot out the exact same energy in one single packet. So the colour depends solely on how much energy in that packet of light emitted. When light is higher energy the more blue it seems, and thats not even the limit. The light can be ultraviolet. Thats why if you weld without proper equipment, you get sunburns.
