RGB Colours

You may hear the term “RGB” when working with a print or web agency, so we thought it would be useful to provide some clarity on the subject since we have covered the subject of website colours recently.

What is RGB?

Simply put, RGB stands for RED GREEN BLUE colours.

It’s one of the most common colour modes used when graphics are created. RGB are eventually converted to CMYK mode when designs are required for print media.

All colours displayed on your screen have an RGB value. Some colours contain more red that blue or more green that red. RGB colours range between 1 and 255 for each RED, GREEN and BLUE value.  These values are combined and translated into a hexidecimal number or value where the first 2 sets of numbers represent red, the second set of numbers represent the green and the last set of numbers represent the blue. The hexadecimal number is the number that your computer understands so it knows how to interpret and ultimately display the colour correctly.

Here are a few examples – see if you can spot the pattern – remember the higher the RED, GREEN or BLUE value, the more of that colour is in the colour we’re trying to create.
