A method of weathering a sample over a period of time, and measuring color shifts of the sample is described. The method includes: (a) weathering the sample over a first interval of time; (b) determining the color coordinates of the sample after the first interval of time; and (c) repeating steps (a) and (b) for at least one successive interval of time until the completion of the period of time. In an embodiment of the present invention, step (b) further includes: (i) measuring the color coordinates of the sample after the first interval of time; (ii) providing access to at least one color master having color coordinates, the access being obtained by means of the color coordinates of the sample; and (iii) comparing the color master with the sample for verification of the color coordinates. Also described is a weathering system for weathering a sample over a period of time, that includes: (a) a means (100) for weathering the sample over a plurality of intervals of time of said period of time; (b) a means (102) for determining the color coordinates of the sample, in each case after an interval of time; and (c) (i) a means (103) for storing the color coordinates of the sample, determined by means (102), after each interval of time, and/or (ii) a means (104) for producing a color image of the sample, from the color coordinates of the sample determined by means (102), after each interval of time.
