From the main menu, you can access the NCS Navigator from the "Navigator" menu option which allows you to explore the NCS colour space. You can also access the Navigator from within the Colour Details page of any colour which leads you directly into the selected colour in the NCS colour space.
Colour space tab
The Colour space tab shows you the NCS hue circle and triangle. You can navigate between different hues by scrolling the circle so that the hue selector marks the hue you are interested in. Once you have found the hue, you can move the pin in the triangle to your chosen nuance within the selected hue. Once you have dropped the pin on your selected colour, you can click on the colour preview above the tabs to navigate to the selected colour.
Nearby colours tab
The Nearby colours tab shows you a zoomed in "bee hive" version of the currently selected colour in the triangle, and allows you to more easily fine tune your selection of colour by modifying the blackness (black +/- symbol), whiteness (white +/- symbol) and chromaticness (chromatic +/- symbol). To modify either of these, simply click on the colour in the direction you want to go in. Once you have found the colour you want, you can click on the colour preview above the tabs to navigate to the selected colour.
