What is the color of the hydrogen gas?
colourless
Hydrogen is a colourless gas – depending on the production type, different colours are assigned to the hydrogen. Green hydrogen is produced by electrolysis of water, using only electricity from renewable energies.
What color does hydrogen gas glow?
Most of us know that radiation from a hot star causes hydrogen gas in a nebula to glow with a pinkish-red color, plus there are often other colors due to different elements. But mostly they’re red. That’s the simple answer.
What colors of light are absorbed?

Which gas produces pink?
Color
| Gas | Color |
|---|---|
| Argon | Violet to pale lavender blue |
| Krypton | Gray off-white to green. At high peak currents, bright blue-white. |
| Xenon | Gray or blue-gray dim white. At high peak currents, very bright green-blue. |
| Nitrogen | Similar to argon but duller, more pink; at high peak currents bright blue-white. |
What are the three colors of hydrogen?
This video looks at the three different types of hydrogen – gray, blue and green – and examines their environmental credentials. Gray hydrogen is made using fossil fuels like natural gas, oil and coal, which emit CO2 into the air as they combust.

What is blue hydrogen and green hydrogen?
Green hydrogen is produced using electrolysis of water, and blue hydrogen utilizes natural gas. Green hydrogen represents a major opportunity for governments and private business to harness a valuable, sustainable energy resource in the coming decades.
What color does yellow absorb?
The color of light absorbed by a pigment is merely the complementary color of that pigment. Thus, pure blue pigments absorb yellow light (which can be thought of as a combination of red and green light). Pure yellow pigments absorb blue light.
Does red absorb light?
If the color of a surface is anything other than white, it means that it absorbs light of some wavelengths. For example, a surface that appears red absorbs yellow, green, blue and violet light, while reflecting red light. Black is the least reflective color, it’s the color of a surface that absorbs all light.
