I'm making a comparison between the model I build and the data (empirical distribution), using various plots, like this:
Histogram and probability densiti function (PDF)
CDF at different axis (Weibull Axis)
The bule color is the data (empirical distribution), the black and red curve is the model.
The problem is that, what color scheme should I chose?
I mean, in the 1st plot, I use black to represent model, but in 2nd, and 3rd plot, I use red instead, because it contrasts better with blue dots. I'm afraid this inconsistancy would result in confusion, because there are only 2 type of data (Model vs. Empirical), yet I used 3 colors:
