What are the different colors of plasma?

Plasma colors vary across the electromagnetic spectrum, indicating different temperatures, densities, and excitations. Here are some common plasma colors and their corresponding temperatures and environments:

1. Blue:

- Temperature: Low to moderate (~10,000–20,000 K)

- Environment: Found in stars like our Sun, fusion reactors, and some regions of the Earth's atmosphere (particularly during aurora borealis and aurora australis).

2. Red:

- Temperature: Moderate (~20,000–30,000 K)

- Environment: Found in the lower layers of the Sun's chromosphere and in certain types of gas discharges.

3. Orange:

- Temperature: Moderate to high (~30,000–50,000 K)

- Environment: Seen in the higher layers of the Sun's chromosphere and in some nebulae.

4. Yellow:

- Temperature: High (~50,000–70,000 K)

- Environment: Found in the transition region of the Sun's atmosphere and in the corona of some stars.

5. White:

- Temperature: Very high (~100,000 K and above)

- Environment: Observed in hot stars, white dwarfs, and supernova remnants.

6. Blue-White:

- Temperature: Extremely high (~200,000 K and above)

- Environment: Found in very hot stars and in the central regions of active galaxies.

It's important to note that these color classifications are based on visual observations and may vary depending on the specific conditions and parameters of the plasma.
