The name of Yellowstone National Park's "Mud Volcano" feature and the surrounding area is misleading; it consists of hot springs, mud pots and fumaroles, rather than a true mud volcano. Depending upon the precise definition of the term mud volcano, the Yellowstone formation could be considered a hydrothermal mud volcano cluster. The feature is much less active than in its first recorded description, although the area is quite dynamic. Yellowstone is an active geothermal area with a magma chamber near the surface, and active gases are chiefly steam, carbon dioxide, and hydrogen sulfide. However, there are some Mud Volcanoes and Mud Geysers elsewhere in Yellowstone. One, the "Vertically Gifted Cyclic Mud Pot" sometimes acts as a geyser, throwing mud up to 30 feet high.
Red Spouter, a fumarole that looks like tomato soup with some cinnamon in it, is an interesting feature that didn't exist before 1959, when a large earthquake at Hebgen Lake, many miles to the west, shook up much of Yellowstone's underground "plumbing" in this region.
I haven't found documentation to this effect, but I guess the color is due to iron content.
A mudpot, mud pool or paint pot is a sort of hot spring or fumarole consisting of a pool of usually bubbling mud.
Mudpots form in high-temperature geothermal areas where water is in short supply. The little water that is available rises to the surface at a spot where the soil is rich in volcanic ash, clay and other fine particulates. The thickness of the mud usually changes along with seasonal changes in the water table.
The mud takes the form of a viscous, often bubbling, slurry. As the boiling mud is often squirted over the brims of the mudpot, a sort of mini-volcano of mud starts to build up, sometimes reaching heights of 3-5 feet. Although mudpots are often called "mud volcanoes", true mud volcanoes are very different in nature.
The mud is generally of white to greyish color, but is sometimes stained with reddish or pink spots from iron compounds. When the slurry is particularly colorful, the feature is then called a "paint pot".

Tourists walk through Hverir, the lunar-like landscape of bubbling mud holes, steaming vents and fumaroles at the far side of Námafjall, in the northerh Mývatn area. The stench of sulphur can be deterring, but a visit is definitely recommended.

Sulphur crystals in a fumarole, or steam vent. The sulphur and other minerals were deposited by condensation of volcanic gasses. These crystals are the monoclinic polymorph of the element. Sulphur Works area. Lassen Volcanic National Park. Shasta Co., Calif.
Furnas is a civil parish in the municipality of Povoação on the island of São Miguel in the Portuguese Azores.

This area of volcanic landscape is rather exciting – think pools of boiling, bubbling water and mud, plumes of hot steam rising into the air from cracks in the earth and that unmistakable stench of sulphur.
Our guide, Gary, walked us around the fumaroles and boiling pools, warning us not to get too close. We could feel the heat from the safety of the designated footpath. Apparently a few accidents have happened in the past and people have fallen into the hot pools and died from their injuries…
Around the caldeiras, we were taken to a series of natural mineral water springs, where we were invited to taste the water. The water tasted progressively "fizzier" as we moved from one spring to the next. It seemed strange to be drinking carbonated water straight from a natural spring.
I was also invited to sniff some very smelly vapours to unblock my nose. (Did not really work…) ;-)

Smiður is a geothermal hotspring in the Geysir geothermal area in the Haukadalur (Hawkdale) Valley in Bláskógabyggð Municipality, District of Arnessysla, southwest Iceland. The area is to the north of Lake Laugarvatn and has hotsprings, fumaroles, mud pools and geysers including Great Geysir and Strokkur.

The Fountain Paint Pot area in Yellowstone has several springs, pools, geysers, a fumarole, and the Fountain Paint Pot. Yellowstone National Park.
This trail is an easy 0.5 mile (0.8 km) loop boardwalk. You will see various hydrothermal features that are expressions of Yellowstone's volcanism. No two features are exactly alike, yet they can be grouped into those with a lot of water (hot springs and geysers) and those with limited water (mud pots and fumaroles).

"A fumarole (Latin fumus, smoke) is an opening in Earth's (or any other astronomical body's) crust, often in the neighborhood of volcanoes, which emits steam and gases such as carbon dioxide, sulfur dioxide, hydrochloric acid, and hydrogen sulfide. The name solfatara, from the Italian solfo, sulfur (via the Sicilian dialect), is given to fumaroles that emit sulfurous gases.
Fumaroles may occur along tiny cracks or long fissures, in chaotic clusters or fields, and on the surfaces of lava flows and thick deposits of pyroclastic flows. A fumarole field is an area of thermal springs and gas vents where magma or hot igneous rocks at shallow depth are releasing gases or interacting with groundwater. From the perspective of groundwater, fumaroles could be described as a hot spring that boils off all its water before the water reaches the surface."
Text from Wikipedia.
Fumaroles are hot steam vents. Red Spouter is a prominent, noisy fumarole in the eastern Fountain Group of Yellowstone’s Lower Geyser Basin. Red Spouter consists of two decent-sized vents. When the water table is relatively high (for example, in the springtime, during and after snowmelt), Red Spouter’s southern vent is water-filled. In later parts of summer, the water table is lower and the southern vent emits steam. The northern vent is usually a noisy steam emitter.

Not noticed any active volcanism whilst there, but careful examination of 2 of my live HDR photos, revealed a fumarole; a small faint solfatara on the right rim of the summit, producing a small puff of steam, plus CO2 & Sulfurous fumes.
There is still an active magma chamber underneath the mountain.
