    Important notes about online color blind tests

    Colorlite online color blind tests help you identify red-green and blue (Tritan) color blindness. You can also test the color blindness of your kids. The Colorlite color blind tests can determine a person’s type and level of color blindness. Among our color blind tests, you will also find an online version of traditional color blind tests like Ishihara, Lantern, Farnsworth D15.

    *** - excellent test | ** good test with some limitations | * - poor diagnostic sensitivity

    Please note that computer based color blindness tests do not give the same results as the original tests (example Ishihara, D15). Computer displays have only three primary colors. The colors of the printed books cannot be simulated by a display.

    Online color blind tests are not suitable for clinical diagnosis!

    Before you start the test:

    • Remove any glasses with colored lenses.
    • Please perform at least the following screen calibration:
      • Set the brightness of your device to maximum (but minimum 75%).
      • If you use any color filter settings (night mode, blue light filter, color blind filter) please turn it off!
      • Do not expose the screen to direct light (best in the dark or with minimal backlight).
      • If you are using a monitor, the contrast should be at least 75% and the color temperature should be set to “warm”.

    About the color blind test

    Keep in mind that this test is not a clinical diagnosis. Only a professional in a controlled environment can provide such a diagnosis.

    The goal of this test is to find where the gap is located in the “C shape” (known as a “Landolt Ring”) and to click on it. The test contains three series of images. The first series determines if you have a red-green deficiency. If you do, the second and third series determine which type of red-green deficiency and its severity. The second series contains purple-blue testing images. These determine if you have a red deficiency (protan). The third series contains purple-green images. These determine if you have a green deficiency (deutan). The number of the first image in the second or third series that you cannot distinguish the gap in represents the severity of color deficiency. For example, if you get 14 out of 14 right, you have normal color vision, 1 - 5 right is severe, 6 - 10 is moderate, and 11 or 12 is mild color vision deficiency. Also, if the purple-blue number is greater than the purple-green number than you may have a deutan color deficiency. If the purple-green number is greater than the purple blue number, than you may have a protan color deficiency. If both of these numbers are equal but you have a red-green deficiency (as determined by the first image series) then you may have a deutan color deficiency.

    Tritan (Blue) Color Blind Test

    Based on the test results, we generate a color spectrum as you may see (and display it next to a normal one). In case of tritan type color blindness, you probably won't notice (too much) difference between the two spectrums, but people with normal color vision will see the difference. The diagnosis and the two spectrums will appear at the end. It is only for tritan type of color vision deficiency.

    How people see color with tritan type of colorblindness

    As the tritan form of colorblindness becomes more severe, a tritan colorblind person will see the following. The blue colors become less vibrant. Yellow is seen as white and green is seen as turquoise. The blue component of the purple disappears and becomes reddish.

    I am colorblind. Let me show you how I see colors.

    You have probably been asked often how you see colors. Now you can show it! Based on the results of your color blind test, color spectrum is generated as you see and display it next to a normal color spectrum. You probably won't notice (too much) difference between the two spectrums, but people with normal color vision will see the difference.  You can take the test now! The diagnosis and the two spectrums will appear at the end. It is only for red-green color vision deficiency.


    How red-green colorblind people see color

    As colorblindness becomes more severe, colorblind people see the following. The yellow range expands until the red and green ranges disappear. The turquoise range turns white (neutral) and the red component of purple disappears, so the purple just looks blue.
