Question: Write a short note on colour blindness in human beings?

Color blindness, also known as color vision deficiency, is a condition where individuals have difficulty distinguishing between certain colors. This condition often arises from an inherited genetic mutation that affects the cones in the retina of the eye, which are responsible for color perception. The most common types of color blindness are red-green and blue-yellow deficiencies. Symptoms can include difficulty differentiating between colors or brightness of colors, and in rare cases, a complete inability to perceive color. The Ishihara Plate Test is a common diagnostic tool used to identify the presence and type of color blindness. While there is no cure for inherited color blindness, filters and specialized eyewear may help those affected to distinguish between certain colors.
