Examining the alternatives to the Hubble Palette

The Great Orion Nebula (M42, NGC 1976) is probably the brightest, most
famous and most imaged nebula in the night sky. About 1,500 light
years away, M42 is a very active and turbulent cloud of gas and dust
and an important star forming region.. There are many hot young stars
(most notably the Trapezium stars which can be seen clearly in these
images) which ionise the surrounding gas. There is also a significant
amount of reflected light which contributes to the wide range of
visible colours.
