The normal hue of the sky during the daytime is a pinkish-red; {{Contradict-inline|reason=Sky color during the day is described as “yellow-brown” in the following sentence.|date=September 2021}} however, in the vicinity of the setting or rising sun it is blue. This is the exact opposite of the situation on Earth. However, during the day the sky is a yellow-brown "butterscotch" color.<ref>{{cite web|url=http://humbabe.arc.nasa.gov/mgcm/faq/sky.html |title=Archived copy |access-date=2005-04-23 |url-status=dead |archive-url=https://web.archive.org/web/20040810170442/http://humbabe.arc.nasa.gov/mgcm/faq/sky.html |archive-date=2004-08-10 }}</ref> {{Contradict-inline|reason=Sky color during the day is described as “pinkish-red” in the preceding sentence.|date=September 2021}} On Mars, [[Rayleigh scattering]] is usually a very small effect. It is believed that the color of the sky is caused by the presence of 1% by volume of [[magnetite]] in the dust particles. Twilight lasts a long time after the Sun has set and before it rises, because of all the dust in Mars' atmosphere. At times, the Martian sky takes on a violet color, due to scattering of light by very small water ice particles in clouds.<ref>[https://www.jpl.nasa.gov/spaceimages/details.php?id=PIA00915 JPL: A Violet Martian Sky]</ref>
Generating accurate true-color images of Mars's surface is surprisingly complicated.<ref>[http://www.badastronomy.com/bad/misc/hoagland/mars_colors.html Phil Plait's Bad Astronomy: Misconceptions: What Color is Mars?]</ref> There is much variation in the color of the sky as reproduced in published images; many of those images, however, are using filters to maximize the scientific value and are not trying to show true color.{{citation needed}} Nevertheless, for many years, the sky on Mars was thought to be more pinkish than it now is believed to be.{{citation needed}}
