Help with deciphering wiring colors for Spa Air Blower

My spa blower went bad, and shopping a replacement. From the photos I attached, it seems like its 120V and not 240V? (this one was wired back in 1987), I see the wire colors seem to be white/white, one is green/blue, and the other looks Red/Black. Now the colors may have faded a bit, but the green/blue seems unusual? So my question is, is this a 120V wiring set up and would the new 1HP blower likely just have green/black/white, and assuming that blue wire is from the old unit, is that unusual to have been connected to the green. hope I made sense

My bad..my wife corrected my color blind tendacies..it is actually 2 different shades of green, not blue. Now I need to figure out the HP on that motor, because that force was just right. The label fell off years ago, and taking apart the motor yielded no numbers or stamps.

If you value your life, you will never rely on wire colors.
