F.A.Q.

We tried to group together the more usual questions we receive about using and interpreting this site data and services. These FAQs are all related to the EasyRGB site and the way we specifically handle color information. If you are searching for more generic information about color, on the Net there are several good sites devoted to color science, physics, psychology, physiology and technology. Check our Links page for a list of handy color FAQ references.

We will be glad to post readings of your colors on our Color Matching page.
Understand that, in order to grant data consistency, we only consider receiving physical samples of your colors (real color cards or fandecks in good working conditions). We cannot accept color readings or numeric data taken or calculated by different instruments or devices.
If you are interested to have your colors displayed, please contact us for more information.
