S-cones

Short cones sensitive to shorter wavelengths, typically associated with the blue part of the spectrum.

M-cones

Medium cones sensitive to medium wavelengths, which correspond to green.

L-cones

Long cones sensitive to longer wavelengths, which correspond to red.

Color perception

The brain's ability to perceive a wide range of colors based on the relative activity of S, M, and L cones.

What is synesthesia?

A condition where stimulation of one sensory style leads to an automatic, involuntary experience in another style.

Grapheme-color synesthesia

A type of synesthesia where individuals perceive letters or numbers in specific colors.

Color blindness

A condition where individuals have difficulty distinguishing certain colors due to defects in one or more types of cones.

Red-green color blindness

It occurs when either the L-cones (long cones, sensitive to red wavelengths) or the M-cones (medium cones, sensitive to green wavelengths) are not functioning correctly, making it hard to distinguish between red and green.

Blue-yellow color blindness

A rarer form of color blindness that involves problems with S-cones and makes it difficult to distinguish between blue and yellow.

Total color blindness

Also known as monochromacy; a rare condition where all three types of cones are defective or absent, resulting in the perception of varying shades of gray.

Inheritance of color blindness

Color blindness is typically inherited in an X-linked recessive manner, making it more common in men than in women.
