A normal human eye can distinguish approximately how many different colours/colors?
Human eye Human eye The human eye is an organ which reacts to light and pressure. As a sense organ, the mammalian eye allows vision. Human eyes help to provide a three dimensional, moving image, normally coloured in daylight. Rod and cone cells in the retina allow conscious light perception and vision including color differentiation and the perception of depth. The human eye can differentiate between about 10 million colors and is possibly capable of detecting a single photon. Similar to the eyes of other mammals, the human eye's non-image-forming photosensitive ganglion cells in the retina receive light signals which affect adjustment
Coat of many colors Coat of many colors In the Hebrew Bible, the coat of many colors ( "ketonet passim") is the name for the garment that Joseph owned, which was given to him by his father, Jacob. According to the King James Version, Genesis 37:3 reads, "Now Israel loved Joseph more than all his children, because he was the son of his old age: and he made him a coat of many colours." The Septuagint translation of the passage uses the word ("poikilos"), which indicates "many colored"; the Jewish Publication Society of America Version also employs the phrase "coat of many colors".
