Morphology

retinal + cone

This is a literal adjective+noun composition: 'retinal' (= relating to the retina) restricts the noun 'cone' (a photoreceptor cell), so a learner who knows both constituents can infer it is a cone cell located in the retina responsible for color/bright-light vision. The relation is compositional and cross-linguistically common, so the meaning is immediately derivable from the parts.

Etymology

Retinal cone gets its name from where it sits and how it looks: retinal shows it is in the eye's retina and cone describes its small cone shape that helps it take in 'bright light' and detect 'color vision'.
