Light curves in g- and r-bands for one SN Ib (SN 2020nke) and one SN Ic (SN 2021bwq), of which (g − r)_rmax values after Milky Way reddening and K-correction are close to the mean values of SNe Ib and Ic without narrow lines. The data points show the observation, the solid lines represent the Gaussian Process fits, and the shaded regions indicate the 1-σ uncertainties. The black arrows show the determined (g − r)_rmax values. The x-axis represents days since the r-band maximum, determined from the fitted light curve.
