G (cyan), G_BP (blue), and G_RP (red) light curves of RR Lyrae stars of different pulsation mode in the LMC and SMC, released in Gaia DR2. The multi-band time-series data are folded according to the period and epoch of maximum light derived by the SOS Cep&RRL pipeline. Although the errors are larger than in the G band, the colour light curves are well defined. The G_BP light curve of the RR Lyrae star in the top right panel is brighter and has a lower amplitude than the G-band curve, likely because the star is blended with a companion that contaminates the G_BP photometry (see Sect. 4.1 for details).
