White is fine. If it's yellow/orange, not good. If it looks like static electricity type spark, no good/weak. Snappy and bright: good. Solid blue can be bad. Bluish white is the "normal" if there is a normal. Also, if it starts up and runs good you don't care what color it is.
Are you having trouble?
