This makes the gas emit light
over a range of
wavelengths, including the
visible, and depending on the atoms which make it up, we see different colours in the nebula.
This reversible dehydration and rehydration, shrinking and swelling, changes the thickness and spacing, which, in turn, changes the
wavelength of the light that's reflected, thus «tuning» the color change
over the entire
visible spectrum.
For many applications such as lighting and illumination, the
wavelength range needs to be
over the entire
visible spectrum and thus have a bandwidth of 300 nm.
The map has been superimposed
over an image of Jupiter taken at
visible wavelengths with the NASA / ESA Hubble Space Telescope.
That's the bit about «albedo» in all of this talk, BTW — it represents the fraction of all the incident light intensity (not just
visible OR infrared, the integrated intensity
over all
wavelengths) that is reflected.
