Different igneous rocks have different silica contents. I could go into loads of detail about mineralogy but what you probably need to know is that magma (as rock is immeasurably viscous as it is solid) containing high Si is more viscous that that with low Si (Silicon being Si). Basalt has low Si, andesite has high Si. Both are extrusive igneous, but form at different plate boundary types.

Which of the igneous rock types has the lowest silica content?
Ultramafic igneous rock contains the least silica.
Relationship between silica content and overall color of igneous rock?
They both are the color of an igneous rock.
Which igneous rock has the lowest silica content?
Felsic Rocks
What is an igneous rocks color mainly determined by?
An igneous rock's color is mainly determined by its silica content.
A light colored igneous rock with silica content and explosive eruptions?
Andesite

Ultramafic igneous rock contains the least silica.
An example of an igneous rock low in silica is granite?
False. Basalt would be an example of an igneous rock with a low silica content.

They both are the color of an igneous rock.
What is igneous rock color mainly determined by?
An igneous rock's color is mainly determined by its silica content.
An igneous rock with a low silica content that flows easily?
No igneous rock flows easily. However, basaltic lava can flow easily, has a relatively low silica content, and turns into basalt, the rock, when solidified.

Basalt.

An igneous rock's color is mainly determined by its silica content.
How the silica content of Molten material affects the color of igneous rock's?
The more silica contained in a rock, the lighter in color it will be.
