Which do you think and why?  Do you know what a granitic rock is?

anonymous · Answer

I think it would be A light colored rock because from what i've seen  granite igneous rocks are not all light i have seen quite alot of dark ones.

e.mccormick · Answer

If you have seen "dark" granite you have been talking to people that sell or use decorative rock and not geologists.  In truth, there is no such thing as "black granite."  that is basalt.  And "darl granite" is diorite.

e.mccormick · Answer

Also, light is a relative term.  The feldspar content of granite can make it pink, green, brown, and a number of other colors.  They just tend to be in the lighter shades, so certainly not A.
