igneous, metamorphic, and sedimentary

A very cool one!
Color and texture is one way to classify igneous rocks. Another way to do this is modal classification and normative classification.
Thomas McKenny Hughes has written: 'Notes on the classification of the sedimentary rocks' -- subject(s): Sedimentary Rocks, Classification 'Geological measures of time'
Rock classification is the process of categorizing rocks based on their physical, chemical, and mineralogical properties. This helps geologists understand the origins and characteristics of different rocks, such as sedimentary, igneous, and metamorphic rocks. Classifying rocks also aids in studying the Earth's history and geological processes.

Preserved coral reefs that have turned into sedimentary rocks are classified as biogenic sedimentary rocks.
No, igneous rocks are not classified by their shape. They are primarily classified based on their origin (either intrusive or extrusive) and their texture (coarse-grained, fine-grained, glassy, etc.). Shape or form is not a major factor in the classification of igneous rocks.
This classification scheme would likely be based on the genesis or origin of the rocks, as plutonic and metamorphic rocks are both associated with processes occurring beneath the Earth's surface (igneous intrusion and metamorphism), while sedimentary and volcanic rocks form at or near the Earth's surface through sedimentation and volcanic activity, respectively.
