Tap any colour to see the LRV an adjoining tread surface must reach for the 30% luminance contrast required under AS 1428.1.
Each insert shows mean dry / wet LRV; the scale plots the dry figure. Both are from the Korb product data sheet and the 2025 stair nosing brochure. Contrast is measured between the nosing insert and the surface around it: the further apart the two sit on this scale, the more contrast you get. A minimum of 30% luminance contrast is required under AS 1428.1. Confirm the figure for your tread before you specify.
