38 Plate Colour Test is the most well known colour blindness test all around the world. It consists of 38 so called Pseudoisochromatic plates, each of them showing either a number or some lines.
According to what you can see and what not, the test gives feedback of the degree of your red-green colour vision deficiency. This test can only be used to detect red-green colour blindness.
The 38 Plate Colour Test, commonly known as the Ishihara Test, is a widely used method for diagnosing colour blindness, particularly red-green colour deficiencies. Developed by Dr. Shinobu Ishihara in 1917, this test consists of 38 plates, each featuring a pattern of coloured dots that form numbers or shapes. Individuals with normal colour vision can easily identify these numbers or shapes, while those with colour vision deficiencies may struggle to see them or see different numbers altogether. This test is simple yet effective, providing a quick and reliable assessment of colour vision capabilities.
