Rhinos are regularly informed that We are Color Blind. Wellllllllllllll, maybe. We see all right, or at least our vision works for Us to the extent that it needs to.
For Us, Color is a cumulative sensation of Presence, combining scent, texture, hearing, taste AND sight. Color doesn’t reduce itself to any one source of sensation.
Rhino Receptors are fine tuned, whatever the source. Or, more accurately, sources.
