What evidence did you observe that proves that elements give off their own unique color spectrum?

• All of the gas tubes produced a full spectrum. (A rainbow.)

• When we looked at white light through a prism, we saw the rainbow.

• Each gas tube gave off its own unique color and color spectrum when we looked at the light through the spectroscope. None of them were the exact same.

• Each gas tube gave off the same color and color spectrum when we looked at the light through a spectroscope.
