When I view my stationery on the web site it seems to have different colors from my original logo design, why?

For best viewing purposes, we use RGB color mode to present the logo samples to you. It is the main standard for all computer oriented graphics, web included. However, when we work on stationery designs, we have no choice but to convert your logo to either CMYK or Pantone colors.
Printers do not work in RGB mode. Slight color shifts may occur. Pantone colors may appear even more different on screen because we match them on the Pantone chart as it will appear when it gets printed. You will get a version of your logo in RGB colors as well. Furthermore, when you print the file the color will change.
