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.

💡 Teacher Tip:
Design inclusive materials that do not rely solely on color—use patterns, labels, and high-contrast visuals to support color-blind students.
