I am currently reviewing the proof of an accepted paper for its publication. I have noticed there is a figure whose colors I have chosen very poorly: one of them is yellow and cannot be seen very clearly and when printing the paper in gray scale it is invisible. Also, there is a Figure in which the order of the legend is not the best possible.
Can I change these two figures without the paper going back to the editor? I would of course only modify the colors of the Figure and the order in which legend appears.
