What is Color Blindness?
Color blindness is a visual condition where a person has difficulty distinguishing certain colors. It occurs when the cones in the retina (cells responsible for detecting color) do not function properly.

Less common types: Blue-yellow color blindness and complete color blindness (very rare)
-
It is usually genetic, but can also be caused by eye injuries, diseases, or aging
Symptoms
-
Difficulty differentiating between certain colors, especially red & green or blue & yellow
-
Trouble reading color-coded information
-
Confusion in tasks requiring color identification
Example in Daily Life

A student may mix up red and green shapes on a worksheet or struggle to read color-coded graphs.
💡 Teacher Tip:
Design inclusive materials that do not rely solely on color—use patterns, labels, and high-contrast visuals to support color-blind students.
