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.

For compatibility reasons this site does not contain frames or applets. The few lines of JavaScript embedded in our pages are used only for data validation of entry fields and are transparents to non JavaScript enabled browsers.
One of our goals, designing this site, was to make it simple and fast to download. We hope to have come close to this goal.
One important part of this site experience is of course on-screen colors. Please check our display setting page for more information about system color configuration.
