Neptune's Great Cold Spot is darker than Jupiter's Great Red Spot. The storm is like a hurricane, made of ice and cold, fast winds.
None. Saturn has a great white spot, Uranus has a dark spot. However, Neptune has a great dark spot [see related link for a picture] which has been compared to Jupiters great red spot, but it is not red.
Neptune's giant dark spot is a large storm system on the planet's surface that was first observed in 1989 by the Voyager 2 spacecraft. It is similar to Jupiter's Great Red Spot and has winds that can reach speeds of up to 1,500 miles per hour. The dark spot is thought to be a region of high atmospheric pressure that creates a darker appearance in contrast to the surrounding clouds.
one of jupiters features are that it surface is mostly made of hydrogen and helium
The Jupiter is BIG RED SPOT and a storm system
No, it is a storm, similar to the Great Red Spot on Jupiter.
Voyager 1 and 2 in 1979
Both Jupiter's Great Red Spot and Neptune's Great Dark Spot are large, persistent storm systems in their respective atmospheres. They are both visible features on the planets that have been observed by telescopes and spacecraft. Additionally, both features are dynamic, changing in size, shape, and intensity over time.

It depends where you're looking from. I think its on the bottom left corner.
Jupiter's giant red spot is really just a giant storm and is sometimes nicknamed Jupiter's Red eye.
The Great Red Spot on Jupiter is large enough to fit approximately three Earths inside it. This storm feature is a massive, high-pressure anticyclonic storm that has been raging for centuries on Jupiter's surface.
