Request: option to colour line and points separately in effect_plot

[ezherman]

Hi Jacob, it is my understanding that in the past, the colors argument changed the colour of the line only. It now changes the colour of the line and the data points - when the line is overlaid onto dense data, it becomes hard to distinguish the line from the data points.

I would like to request the option to colour the line and points that come out of effect_plot separately.

I have tried to edit the colour of the line with downstream ggplot commands (e.g. scale_colour_manual), however this was not successful.

For example, here is a plot from my teaching materials in which effect_plot is used extensively:

Thanks in advance!

Thanks for including the option line.colors in the latest version of jtools!
