how to use ksdensity as a 3D info (color) on a 2D line plot

Hi,

I did a multi (500+) simulations of the same event. I plot the enveloppe of these results (see picture)

now I want to use color to add a new info, the density on each day of sims, something looklike the next picture.

I try ksdensity to define an empiric density but Im not abale to plot the both idea on a same graph...
