Difference in projected density-shape correlation function between the g − r and r − i filters (blue and orange points respectively). The x-axis shows the transverse separation of galaxy pairs. For reference, the signal measured in r-band is shown with grey points, with errors obtained from 3D jackknife resampling. The in-line figure is a zoom-in on the last four data points, in the highest separations. Points are horizontally displaced for clarity.
