ColorMunki Smile is a simple colour calibration solution that makes sure your LCD & LED displays/monitors - laptop or desktop - are displaying the correct colours. Colour can vary from monitor to monitor or change over time. Smile includes a measurement device and simple software, with easy-to-follow help videos, to adjust your screen to show the colours correctly. It allows you to calibrate one or more monitors for colour consistency, and a reminder will notify you when it is time to re-calibrate your display.
