The mission's first map of Pluto is in approximate true color-that is, the color you would see if you were riding on New Horizons. At left, a map of Pluto's northern hemisphere composed using high. These images revealed much of the surface of Pluto to be covered in a vast, heart-shaped glacier of nitrogen ice, while the planet's atmosphere - composed mostly of nitrogen, methane and carbon dioxide - appeared blue.
So the most accurate answer to the question What colour is Pluto? is, It depends where you're looking from". Why is Pluto Rainbow? Unveiling the Color Palette of the Distant Dwarf Planet Pluto isn't literally a rainbow; however, recent observations reveal a complex and varied surface showcasing an array of colors, from reddish-brown to yellows and blues. This article explores why Pluto exhibits this diverse color palette, revealing the fascinating processes that shape its frozen landscape and how.
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. 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. The color of the atmospheric haze presents an apparent paradox, as it appears distinctly blue when viewed against the blackness of space. This blue color is also caused by the tholin particles, which are small enough in the upper atmosphere to scatter blue light much more effectively than red light, similar to how Earth's sky works.
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. 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.
This single color MVIC scan includes no data from other New Horizons imagers or instruments added. The striking features on Pluto are clearly visible, including the bright expanse of Pluto's icy, nitrogen-and-methane rich heart, Sputnik Planitia.

However, keeping in mind what Pluto's real colors look like, there's no reason we can't appreciate the blue-red image as well. This high-resolution, false color image of Pluto is my favorite.
