A CONVENIENT DIGITAL REFERENCE
Physical Munsell colour charts remain important tools for geological, soil and environmental work, but they are not always convenient to carry or quick to search. GeoColour provides an accessible digital companion on a device already carried in almost every pocket.
IMPORTANT COLOUR NOTICE
GeoColour displays digital screen representations of physical Munsell reference colours. Colour appearance can vary between devices due to display calibration, brightness, viewing conditions and other screen characteristics.
GeoColour is intended as a convenient, searchable reference. Where precise scientific colour matching is required, a calibrated physical Munsell colour chart should still be used.
