    Hi isla14680! Welcome to the Milky Way 😃 The these are different emission regions within the same nebula. It's useful to be able to separate out the different wavelengths of light within the infrared images so a colour scheme has been chosen to allow the scientists to do this. This post by team member gwolfchase is really useful. Follow the links to the GLIMPSE site.

    So to answer your question 😃 the green gas represents a wavelength of 4.5 microns and pink (from a previous comment by a team member) represents neutral rather than ionised gas.
