All nerve tissue is grey by default due to a lack of any pigmented organelles as they would be almost usless. The white matter on the other hand is white because of an insulator wrapped around it called myelin which is made of fat. The grey matter is the cell bodies of the neurones ans so there is little need for insulation but the white matter is the axons and thus and insulator is present to speed up the action potential.
What else can I help you with?
Where is the white matter located in relation to the gray matter in the spinal cord?
The white matter is located on the outside of the gray matter in the spinal cord.
Is the brainstem white matter or gray matter?
The brainstem contains both white and gray matter. White matter is found on the inside, made up of myelinated nerve fibers, while gray matter is located on the outside and consists of nerve cell bodies.
Does the hippocampus count as gray or white matter?
The hippocampus is primarily composed of gray matter, which consists of cell bodies, dendrites, and synapses. White matter, on the other hand, is made up of myelinated axons.
Is the corpus callosum composed of white or gray matter?

It is superficial to the white matter.

gray matter
What does gray matter lack that white matter has?
Myelination
Does anterior commisure consist of gray or white matter?
gray
What does not go gray matter white matter myelin fiber track?
Gray matter doesn't fit. White matter is white because it has myelin covering the axons. And the myelin fiber tract is "white" for the same reason.
The portion of the spinal cord made up of myelinated axons?
White Matter
