7 colors come randomly must be matched to complete a level! (red, orange, yellow, green, turquoise, blue and purple).If the colors match, click the 'Matched! Get the next color' button!.Complete one difficulty level takes about 1-2 minutes, the full game about 5 minutes. The game can be interrupted at any time because the results are displayed by colors to colors. The difficulty of the game is changed by reducing the lightness of the colors. The saturation and lightness is fixed while the hue can be adjusted. The task is to match basic colors (red, orange, yellow, green, turquoise, blue and purple). The purpose of the game is to help to understand better the characteristics of your color vision and not to diagnose color blindness! Description of the game The blue component of the purple disappears and becomes reddish. Yellow is seen as white and green is seen as turquoise. How people see color with titan type of colorblindnessĪs the tritan form of colorblindness becomes more severe, a tritan colorblind person will see the following. The test detects tritan type of color blindness with adequate efficiency. Based on my measurements, the online tritan color blind test has a lower efficiency than the original Colorlite test book (96.25%), however, this difference is still acceptable. The number of errors allowed is 2, The test has a sensitivity of 84.21%, a specificity of 95.83%, a positive predictive value of 94.12%, and a negative predictive value of 88.46%. The maximum score available on the test is 10. Sensitivity of the Tritan (blue) color blind test The diagnosis and the two spectrums will appear at the end. It is only for tritan type of color vision deficiency. 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 test contains a series of images. Based on the test results, we generate a color spectrum as you may see (and display it next to a normal one). 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. Only a professional in a controlled environment can provide such a diagnosis.
Keep in mind that this test is not a clinical diagnosis. START About the Tritan (blue) color blind test If you don't have Colorlite glasses already, please contact us! Contact Do this exercise daily until you can name each color correctly. If you did not name the color correctly, try memorizing it and continue with the other colors. Name the first color and press the "Show me…" button. Start the exercise only when you see the white colors as white through the glasses. Wear the glasses for at least 5 minutes before exercising as to allow for color adaptation. This color naming exercise helps you develop the uncertainty in color identification ability. Without the correction glasses, the exercise is pointless. The following exercise is to help our customers, who are already wearing our correction glasses and would like to improve their color naming ability. You would still need to learn to identify (name) new hues never seen before. (After color adaptation that takes about 2 minutes.) However, the improvement in color identification ability is not yet spectacular. In the majority of cases, there is an immediate improvement in color discrimination with the Colorlite colorblind correction glasses. Colorblind people can only partially learn this ability. Color identification abilities begin in childhood and develop slowly as more shades are recognized over time. (Example: the grass is green, the sky is blue.) Nevertheless, without the help of the environment, it would be challenging. However, many colors are correctly named with colorblindness, because they have been learned. Good color discrimination is a prerequisite for color identification, as it is impossible to name colors properly unless we can distinguish them. While people with normal color vision can distinguish millions of hues, the colorblind can barely see a few hundred.
Colorblind people have problems within both areas.
The two main characteristics of color vision are color discrimination and color identification.
