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.

What can I do using the services of this site?

The purpose of this site is to give users practical suggestions about real life colors matching computer generated RGBs.
Every day architects, graphic designers, painters, everybody using home improvement software, generate new colors on their computers. As long as they do not need to translate their colors in real products, RGB values are OK.
But what if an architect does want to spec a paint for his project?
What if a designer does need to print his artwork?
What if you have to specify the color of your company logo to an advertising company?
These are the occasions where RGB values are useless, specially if physical color standards are not available at the moment.
This site is here to fill the gap in between computer generated colors and real world colored products.
For professional in the color industry we also introduced a powerful color calculator to convert color data in different color spaces. If you don't know what XYZ are, don't worry, this is stuff for the color lab experts.
