Limitations on Use of the Urine Color Chart

If you purchase one or more wall charts, you must agree to certain limitations on the use of the wall chart. Your signature certifies that you promise to abide by these limitations.

The urine color chart is registered with the U.S. Patent and Trademark Office (10/30/2012), and with the European Office for Harmonization in the Internal Market, Trademarks and Designs (7/24/2013).

Research and Nonprofit use of the Urine Color Chart

A limited number of color charts are distributed free of charge, for research purposes or for use by small nonprofit organizations. Each request will be considered on an individual basis.

Using the Color Chart

We recommend the following approach:

  • Check your urine color score two or more times each day. When two consecutive measurements (separated by at least one hour) agree, you can trust that value.
  • It is best to evaluate urine color when water intake and loss have been stable for a few hours.
  • It’s easy. Simply follow these steps:
    1. Collect a small urine sample in a clear container.
    2. Hold your sample up to a light source and compare urine color to the colors in the chart.
    3. If your urine score is
      • 1, 2 or 3 - you are very well hydrated
      • 4 - you are normally hydrated or slightly dehydrated
      • 5 or 6 - you are dehydrated
      • 7 or 8 - you are extremely dehydrated
    4. If you determine that you are “slightly dehydrated”, “dehydrated”, or “extremely dehydrated”, you should consume more water during the next 24 hours. Don’t overdo it. Simply drink a few extra cups of water with meals and at a few other times throughout the day, until your urine color returns to normal.
    5. Precaution: Research analyzed for men in 2010 (1) and for women in 2011 (2) indicates that a urine color of 1 or 2 is rare (1 – 5 % of all human samples). This is not a reasonable goal for your daily hydration plan. It’s O.K. once in a while, but not every day. Remember that drinking too much water can make you ill, or may even result in hospitalization. Adequate water is essential, but don’t overdo it.

Wall Chart Reproductions
The colors in the urine color chart have been tested in numerous research investigations. These colors have been selected precisely and even slight differences in color can alter the interpretation of hydration status. This explains why we do not offer the urine color chart online. Different versions of computer software, computer monitors, and computer printers generate color charts that contain incorrect, invalid colors. Thus, to maintain validity and to ensure that your hydration state is assessed accurately, we offer the color chart only by mail.
