'''Reseptor warna''' atau sering juga disebut '''sel kerucut''' ({{lang-en|cone cell}}) adalah sel penerima sinar di dalam [[retina]] mata yang bertanggung jawab terhadap penglihatan warna. Sel kerucut akan bekerja dengan baik pada kondisi yang cukup terang. Sebagai lawannya, sel batang akan bekerja dengan baik pada cahaya yang redup.
Osterberg pada tahun 1935 mengatakan, ada sekitar enam juta sel kerucut pada mata manusia.<ref name="Osterberg">G. Osterberg (1935). “Topography of the layer of rods and cones in the human retina,” Acta Ophthalmol., Suppl. 13:6, pp. 1–102.</ref> Sementara Curcio pada tahun 1990 mengatakan ada sekitar 4,5 juta sel kerucut dan 90 juta sel batang pada retina manusia.<ref>{{cite book|title=The human eye: structure and function|url=https://archive.org/details/humaneyestructur0000oyst|last=Oyster|first=C.

Sel kerucut kurang sensitif terhadap cahaya dibandingkan sel batang, tetapi sel kerucut mampu membedakan warna. Sel kerucut juga dapat melihat detail yang lebih halus dan karena memiliki respon yang cepat terhadap perubahan.<ref name="Kandel">{{cite book

Karena manusia biasanya memiliki tiga jenis sel kerucut dengan iodopsin berbeda, yang memiliki kurva respon yang berbeda, dengan demikian manusia menanggapi variasi warna dengan cara yang berbeda. Hal ini yang mebuat manusia memiliki penglihatan [[trikromatik]]. Pada kasus but warna, satu atau lebih sel kerucut tidak berfungsi sebagai mana mestinya, sehingga penderita buta warna tidak bisa melihat warna tertentu.
Pernah juga di laporkan bahwa ada manusia yang memiliki empat atau lebih sel kerucut yang membuat mereka memiliki penglihatan [[tetrakromatik]].<ref name="Jameson 2001" >{{cite journal

One of the diseases related to cone cells present in retina is Retinoblastoma. Retinoblastoma is a rare, cancerous tumor of a part of the eye called the retina. Cancer of the retina common in children which is caused by the mutation of both copies of retinoblastoma genes (RB1).
-One or both eyes may be affected.
-They pupil may appear white or have white spots. A white glow in the eye is often seen in photographs taken with a flash. Instead of the typical "red eye" from the flash, the pupil may appear white or distorted.
