Color-color plots showing ${\alpha }_{54}^{144}$ vs. ${\alpha }_{144}^{817}$ (left column), ${\alpha }_{54}^{144}$ vs. ${\alpha }_{817}^{1269}$ (mid column), and ${\alpha }_{144}^{817}$ vs. ${\alpha }_{817}^{1269}$ (right column) for the three galaxies (rows). The color of the points corresponds to the projected distance along the tails. The black line shows the power-law scenario and the dotted blue line the JP aging model.
