In general how does the density of a light colored igneous rock differ from that of a dark colored igneous rock?

Light-coloured igneous rocks, such as granite, have a higher silica content and lower iron and magnesium than darker ones, such as basalt.
Since iron and magnesium are very dense minerals, this makes darker igneous rocks more dense than lighter ones.

Normally, light colored igneous rocks are less dense compared to dark colored igneous rocks. This is because the light colored rocks have a less iron in them.

Does the density differ in a hurricane?
The density of materials is unchanged.
How do light colored rocks and dark colored rocks differ in composition?
Light colored igneous rock is called felsic, and is high in quartz, muscovite mica, and orthoclase feldsparcontent. Dark colored igneous rock is called mafic, and contains a lesser amount of silica along with olivine, pyroxene, amphibole, biotite mica, and plagioclase feldspar.
Why do rocks sometimes have different colored specks and different markings?

Would two blocks made of the same metal but differ in sizes differ in density?
Density is dependent on two things - the volume of the object under consideration, and it's mass. For a given material, in order for the volume (the size) to change, so must the mass by a proportional amount. Therefore, for a specific material, changing the size of the sample does not affect the density in any way.

How do Metamorphic and Igneous Rocks differ?
Metamorphic rock differs from Igneous rock by, Metamorphic rock forms when sedimentary and igneous rocks change under heat and pressure. Igneous rocks form as lava cools and hardens.
