There are a large number of variables which can affect the colour produced in Full Colour Printing. Simply looking at the appearance of colours on a monitor - especially if no monitor calibration has been carried out - is unlikely to produce predictable printed results.
In just the same way an un-calibrated desktop printer, such as a laser or inkjet may well produce very different colours to those produced on a professional printing press.
It is much better to choose and use colours from printed swatches since these give an accurate representation of what the finished result will be.
