Terms of Use:  ColorDx Test


1. Background

Color vision testing is an assessment of a person’s ability to accurately discriminate between “confusion colors” which are specific matched sets of colors that are scientifically calculated to be confused by persons with diminished color perception(s).  A person who is color vision deficient sees many colors, but certain colors are viewed as being equivalent that a color normal person would view as distinctly different.  Color vision deficiency is commonly and inappropriately called “color blindness”, however they are usually not blind to color, but have reduced discrimination to some colors.  ColorDx applications, or web-enabled applications (the “Applications”) are designed for a person to take a test, with little supervision culminating with a written report describing the type of colors that are confused (described as Protan, Deutan, and Tritan) and the severity based upon how many images cannot be successfully identified. ColorDx tests have been validated by the Naval Aerospace Medical Institute for use in qualification of Naval and other armed services pilots and other service personnel.



Some jobs, military qualifications, and professions require normal color perception for safety or performance-precision of visual recognized tasks.  A test subject that would have another person either:  

  • Fraudulently take the test directly, mis-identified as the test subject; or, 
  • Provide any test answers or assistance in identifying any test answers;

would likely be held liable for falsifying personal information for personal gain and fraudulent medical evidence.  Such fraudulent test practices invalidate the test results.

The test subject, by consenting to take the ColorDx test, certifies that they have:

  • Accurately identified themself as the true test taker;
  • Received no help, assistance, hints, or direction from another person as to what is seen on any of the test plates or the color normal test answer.


3. Required Test Conditions

All color vision tests are subject to proper test conditions for maximum detection of color vision deficiencies.  Color vision tests, including ColorDx Applications performed under sub-optimum conditions may allow low grade or “mild” color deficient persons to pass or perform slightly better than would be expected.  The same sub-optimum conditions are unlikely to degrade color vision normal individual’s results to be reported as color vision deficient. 

For optimal results, color vision tests should performed:

  • In low or moderately illuminated environment free of strong external light sources or reflections (printed color vision tests should be administered under an illuminant C or D approximate 6,500 Kelvin color temperature lamp).
  • LED back-lit monitor with 6,500 Kelvin color temperature.
  • A current color calibration is recommended for optimized results.


4. Acceptance of Terms of Use

By taking a ColorDx color vision test, the test taker acknowledges that they have personally taken the test without aid, coaching or help; and hereby releases from liability and agrees to indemnify and hold harmless Konan Medical USA, Inc. and Waggoner Color Vision Testing, LLC. and its employees, representatives, contractors, and agents (hereinafter the “Companies”) for any and all liability for damages resulting from the use of a ColorDx Application.  Optimal sensitivity of all color vision tests are achieved using a color-calibrated monitor or targets illuminated with a 6500 K lighting environment.  Sub-optimum test conditions my result in False Negative results (minor color deficiencies resulting in a PASS result), primarily for low-severity color deficiencies.  False Positive results (FAIL result with no color deficiency) are unlikely to be reported from the same sub-optimum test environment. Persons relying upon this test summary for vocational, safety, or any color critical task, by presentation of these results certify that:  they personally took this test; the results were achieved without any external aid; and test was taken under optimum conditions.
