Rest-frame LSST color curves for 10 000 random SN positions in the magnification map with κ = 0.36, γ = 0.35 and s = 0.5, comparing microlensed color curves (with median in solid red, and 1σ and 2σ band in different shades) to non-microlensed ones (dotted black). The vertical black lines indicate the duration of the achromatic phase. We find different durations of the achromatic phase for different SN Ia models, where the N100 model in this specific case has the shortest and the merger model the longest duration. This is just a specific case to illustrate the dependency of the achromatic phase on the specific intensity profiles. More general conclusions can be drawn from Figs. 6 and 7.
