from The American Heritage® Dictionary of the English Language, 4th Edition
- n. An incandescent, transparent layer of gas, primarily hydrogen, several thousand miles in depth, lying above and surrounding the photosphere of a star, such as the sun, but distinctly separate from the corona.
- n. A gaseous layer similar to a chromosphere around a star.

- n. The faint pink extension of a star's atmospheric envelope between the corona and the photosphere

- n. An atmosphere of rare matter, composed principally of incandescent hydrogen gas, surrounding the sun and enveloping the photosphere. Portions of the chromosphere are here and there thrown up into enormous tongues of flame.
from The Century Dictionary and Cyclopedia
- n. A rose-colored gaseous envelop around the body of the sun, through which the light of the photosphere passes, and from which the enormous red cloud-masses of flames of hydrogen, called solar protuberances, are at times thrown up. Also chromatosphere, color-sphere, and sierra.

Sorry, no etymologies found.
After the chromosphere is the corona which is much larger than the previous layers of the Suns atmosphere and extends far out into space.
Above the chromosphere is a transition region where the temperature rises rapidly to about one million degrees Kelvin.
Above that layer, where the gas is thinner (in a layer called the chromosphere), the hydrogen does emit light at specific colors.
The gaseous envelope from which the prominences spring has been called the chromosphere on account of the coloured lines displayed in its spectrum.
Below the chromosphere is the photosphere, the lower envelope of the sun, if it be not indeed the body of the sphere itself; from this comes the light and heat of the mass.
Below the corona and sharply separated from it the observer finds another body of very dense vapour, which is termed the chromosphere, and which has been regarded as the atmosphere of the sun.
The chromosphere is a cool, obscure that lies just above the photosphere.
The layer outside the photosphere is known as the chromosphere, which extends several thousand miles beyond the photosphere.
What we now call the "chromosphere" is an envelope of glowing gases, by which the sun is completely covered, and from which the "prominences" are emanations, eruptive or flame-like.
"chromosphere" with "prominences" of various forms and dimensions rising high above the solar surface; and over, and embracing all, is the
