What Color Is Helium?

Helium is a colorless and odorless gas in its natural state. It gives off a blue neon color when burned. When an electric current runs through it, helium is a pale peach to orange color.

Helium is nonreactive and lighter than air, which makes it ideal for use in weather or decorative balloons. Helium is used to keep satellite instruments, spacecraft and MRI machines cool. After hydrogen, helium is the second-most abundant gas in the universe. It is present in all stars and has no known biological role. Helium is nontoxic and used by deep-sea divers at a rate of 80 percent helium and 20 percent oxygen.
