The Choroid is black because its heavily pigmented because of an excess of melanin.
Also, the dark colour of the choroid prevents internal reflection in the eye, so to ensure the image received is not blurred.
Because otherwise the images would be faded
So that it doesn't reflect light and absorbs it instead. If that didn't happen, everything would seem faded.
The black pigmented lining called the Choroid, on the inside of the eye.
Choroid Plexuses
Damage to choroid plexus would interfere with the production of CSF (cerebrospinal fluid).
Well, the theory right now is the majority of CFS is produced within the ventricles the choroid plexus produces by a combined process of diffusion, pinocytosis and active transfer of arterial blood and the rest is produced by modified ependymal cells of the choroid plexus.
This is the middle layer of the eyeball and it is composed of the choroid, ciliary body and iris.
choroid is black in colour with a lot many nerve fibres to nourish the organ that is eye.

what are choroid bodies?
Choroid Plexuses
One of the two muscles that make up the front part of the choroid is the ciliary muscles. Another one that makes up the choroid is the iris.

The choroid layer in the eye has a black color pigment on it. Also, the light entering the eye is not reflected because light rays entering the pupil are absorbed by the tissues inside the eye.

The choroid forms the bulk of the heavily pigmented vascular layer.
