Here's the breakdown:
* Basaltic rock is a type of igneous rock, formed from cooled and solidified lava or magma.
* Basaltic rocks are typically dark gray to black, although they can also have shades of green, brown, or even a purplish hue.
* The color of basaltic rock is influenced by the minerals present. The most common minerals in basalt are pyroxene and plagioclase feldspar, both of which tend to give the rock a dark color.
* Weathering can also affect the color of basalt, making it appear more brown or reddish.
So, to answer your question directly, basaltic rock will usually appear dark gray to black, though it can have variations in color depending on the specific minerals present and the effects of weathering.
