There is no chemical element that gives it its dark color, but rather minerals, which are compounds. Andesite's dark color is due to the presence of pyroxene and some hornblende.
What else can I help you with?
What gives basalt its dark color?
Andesite gets its dark colour from the way its crystals stick together.
What chemical element gives diorite its light colour?
The light color of diorite is predominantly derived from feldspar minerals, particularly plagioclase feldspar. Plagioclase feldspar is a group of silicate minerals that can range in color from white to light gray, giving diorite its characteristic light color.
What is the streak color of andesite?
dark gray, brown, greenish
Which type of volcanic material appear dark grey?
andesite
Is blue still blue in the dark?
Technically no colour is present absent light since it is light that gives anything colour.
Dark fine grainmed volcanic rock consisting of plagioclase feldspar?
andesite
What is the color of a Andesite rock?
The dominant color of the andesite is black with some spots of red and gray. from: http://192.211.16.13/curricular/MN/tieton_andesite.htm
Does andesite thus have more or less dark minerals?
That depends on what you are comparing it to. It has more dark minerals than rhyolite but fewer than basalt.
What kind of rock andesite?
No. Andesite is classed as an 'intermediate' rock, being halfway in composition between a mafic and felsic rock. Mafic rocks are those that contain alot of ferromagnesian minerals (iron and magnesium) which give mafic rocks their dark colouring. Typical ferromagnesian minerals include olivine and pyroxene. Typical mafic rocks are basalt and gabbro. Felsic rocks, on the other hand, are low in magnesium and iron and are usually light in colour, such as granite and rhyolite. Andesite therefore typically contains a mixture of both felsic and mafic minerals and is classed as 'intermediate'.
Which rock has an intermediate composition?
Andesite is a rock with an intermediate composition. It contains minerals such as plagioclase feldspar, amphibole, and pyroxene, giving it a balance between light and dark minerals. Andesite forms from the cooling of magma with a composition between basalt and granite.

You never use colours that clash. You want to be able to see your data. So you either have a dark colour on a light background or a light colour on a dark background.

What is an andesite?
a dark, fine-grained, brown or grayish volcanic rock that is intermediate in composition between rhyolite and basalt.
