Astronomers in Maryland have worked out the colour of the universe.
They say if all light could be viewed at once it would look turquoise.
They made the discovery by combining the colours of all known galaxies
and worked out the average.
Karl Glazebrook, an assistant professor of astronomy at Johns Hopkins
University, said: "The colour is quite close to the standard
shade of pale turquoise, although it's a few percent greener."
He and his colleague Ivan Baldry revealed their findings at a presentation
of the American Astronomical Society.
Glazebrook says: "From one perspective, it's surprising that
it turns out to be greenish, because there are no green stars. But
it's the large numbers of old red stars and young blue stars in
the universe that gives us the green."
Although this might puzzle people used to mixing paint, light sources
combine in a different way to pigments.
The scientists say the universe probably started with a "blue
period", before a "green period" and will eventually
have a "red period".
Linda Barker of TV's Changing Rooms told Ananova: "Turquoise
is an appropriate colour really because it is very spiritual.
"It is popular, fresh and contemporary and goes well with
metallics but I'll look at it in a different way from now on."
