## Description

This Android Application is a beta version as a proof of concept. It evaluates the difference between two LRVs (Light Reflectance Values) according to FprEN 16584-1:2015. LRV measurements are carried out with the Node+Chroma. Michelson contrast is obtained from the LRVs whereby the standard deviations are taken in consideration. Accordingly, the pass / fail criterion and the probability for fulfilment of FprEN 16584-1:2015 are displayed in the graph. LRV or L*ab values can also be directly entered (without use of the Node+Chroma). No warranty can be given for the use of this software and it can only be applied at the users own risk.
