The lightness of a NCS color pattern can be determined by visual comparison with the samples of this black-and-white reference scale.
Punched map in the format (open) 41 x 9.5 cm, with 18 grey samples from the NCS color sample collection. The punching out enable an apply on the color surface and thus a judgement with the introduced grey fields.
The lightness meter provides details of the lightness number L, the huminous reflection factor Y and the NCS notation for each of the 18 grey samples.
