It is important to calibrate the screen of your electronic device before you attempt to colour grade a gemstone using ColourWise. We recommend that the screen resolution is set at 1280 x 1024 pixels or higher with a 'Colour Quality' of 16 bits or higher.
To calibrate your screen, take a screenshot of the three colour samples (RED, GREEN & BLUE) and upload these using the link below. This program will analyse the colours. ColourWise uses HTML5 generated digital imagery. This is supported by all the main browsers and is displayed the same way 'text' is generated. This ensures 'truer' colours. The 'colour analysis' should match very closely the RGB values listed. If the RGB values do not mtach, you will need to go into the 'Display' settings of your device and change the colour calibration.
