Stochastic effects on colors and ages of clusters. First row: two color diagrams for a stochastic sample of clusters with different masses and different ages. The dashed line represents Padova 2008 SSP models of solar-like metallicity. Second row: U − B color evolution. Third row: V − I color evolution. Fourth row: density plot to make a comparison between input and output ages. The red line represents the 1:1 relation, not a fit to the data.
