Colour–magnitude diagrams of the IC 4665 open cluster: (absolute G, G − G_RP, left) and (absolute i, i − Ks, right). The PARSEC+COLIBRI (solid line) and the BT-Settl (dashed line) isochrones of 30 Myr are overplotted. The members are shape- and colour-coded according to their membership classification: red circles for members in GDR2 and DANCe analysis, blue left-pointing triangles for members only in GDR2, and green right-pointing triangles for members only in DANCe.
