This image uses the same data as the other image of the same object. The luminance of the image is still provided by the narrowband data, as it is best used on stellar nurseries to reveal details.
However, this time the colour comes from data gathered by broadband red, green, and blue filters to better illustrate how we, with our human eyes, would percieve it. The outstanding red colour comes from the dominance of hydrogen in the nebulosity which emits dominantly in the red spectrum, but also helped by sulphur which also emits red. The blues and even greens that you see here are sourced more from light reflected (rather than emitted) from stars off of dust and gases.
