Consistent colors

This may be simple, or impossible. I'm creating multiple line charts all on the same page, so that it is easy to see comparisons from year to year.
I want the same color themes on all the charts. So I selected the same theme, but it doesn't make the lines the same color. In other words I have three lines on data on each chart. The same three lines of data. I want them to be the same corresponding colors on each sheet. So if monthly income is green, daily, blue, and validations yellow, I want that same scheme on all the charts. That's not what's happening when I select the same theme for each. Is there a way to do this? or a way to select each line and choose that color to make it?
