Each colour has a unique NCS notation to describe how the colour relates to the four basic colours – yellow, red, blue, and green, as well as to black and white – in blackness, whiteness and chromaticness. The NCS code describes the percentage of the colour that consists of these different parts. This makes it possible to describe the colours of all surface materials and ensure that the colours turn out exactly as you want them too. The Colourpin app makes defining and exploring colours an organized and simplified process. Download the new free Colourpin app and start pinning colours already today! For every colour you pin, you get colour information in the form of the closest NCS notation, translated into RGB, L*a*b* and lightness values.
