Rhyolite can come in a wide range of colors, but the most common are:

* Gray

* Pink

* Red

* Brown

* White

The color of rhyolite is determined by the minerals present in the rock. For example, pink and red rhyolite often contain iron oxides, while gray rhyolite is usually rich in quartz and feldspar.

It's important to note that rhyolite can also exhibit other colors depending on the specific mineral composition and geological conditions.
