Your logo or website can be designed using any combination of RGB colors. RGB stands for Red, Green, Blue. These colors output to computer monitors and ink jet printers. All computer screens will show slightly different colors so the table below should only be used as a rough guide. RGB color is best used when the design is going to be used on a web site. These colors are expressed in the hexadecimal numbering system. Professional printers use CMYK and Pantone colors so you should consider that too if your logo design is for print use.
