Which planet is described as blue, green, teal?

• A. Mercury
• B. Mars
• C. Uranus
• D. Venus

Answer: (C)

Planets show their colors by the light their atmospheres and surfaces reflect. Uranus looks blue-green or teal because its atmosphere has methane, which absorbs red light and reflects blue and green wavelengths. That combination creates the pale blue-green hue you can see from Earth. Other options don’t share that color: Mercury is a gray rocky world, Venus appears bright yellow-white from thick cloud cover, and Mars is famous for its red-orange iron oxide surface. So the blue-green-teal hue points to Uranus as the best match.
