Pluto Colour Name
Thanks to the New Horizons mission, which conducted the first detailed study of Pluto in 2014, we know that Pluto's color is rather diverse, with patches of white, yellow and reddish. New Horizons scientists combined the latest black and white map of Pluto's surface features (left) with a map of the planet's colors (right) to produce a detailed color portrait of the planet's northern hemisphere (center).

Although. The colour of Pluto depends on how you observe it, but New Horizons and Hubble have revealed the dwarf planet's rich typography and hues. From the slate gray of Mercury to the ruddy brown of Pluto, the worlds in our solar system are a veritable rainbow of colors.

But what makes them all look so different? What colour is Pluto? Short answer: Reddy-brown. Long answer: Before 2015 we didn't have close-up photos of Pluto and it was hard to tell exactly what colours we might find there. We did know that Pluto is generally reddish but we were very vague on the details.
When the robotic probe New Horizons flew past Pluto in 2015 it took enough photos to give us a good look the dwarf planet's colours. The Discovery of Pluto's Color The discovery of Pluto's color dates back to the 1950s, when astronomers first began to study the planet using telescopes. Initially, Pluto appeared as a faint, grayish-white dot in the sky, but as technology improved, scientists were able to gather more detailed information about its color.
Pluto Size And Color
In the 1970s, astronomers used spectroscopy to analyze the light. Pluto's surface has three primary color hues: red, white, and blue. This is due to the complex chemistry of its icy terrain and atmospheric processes.
The red areas, such as Tombaugh Regio, are caused by tholins-complex molecules formed when ultraviolet (UV) light from the Sun interacts with methane (CH₄) in Pluto's thin atmosphere. These molecules then settle onto the surface. Pluto, the dwarf planet, has a fascinating and varied color palette.

It primarily appears to be a reddish-brown color, but this can differ depending on the region being observed. Some areas on its surface display a lighter tone with a yellowish hue due to the presence of nitrogen ice and varying levels of methane ice. Pluto, a dwarf planet, exhibits a captivating array of colors, ranging from pale white to dark red, due to the complex interactions between its surface composition and the feeble sunlight it receives.
Nitrogen ice dominates the surface of Pluto, which is a key factor in defining its albedo or overall brightness, while methane frost contributes to the planet's distinct reddish hues. Pluto's color is predominantly reddish-brown, influenced by chemical compounds like tholins and hydrocarbons. The presence of methane on the surface gives Pluto a reddish hue, as methane absorbs blue and green light, reflecting longer wavelengths corresponding to red light.
