I have the follwing plot that I generate:
Instead of having the background be white, i want the peaks of the curves to be white and as they increase in value, I want them to get darker. Does anyone have suggestions for this. The code and data file generates is linked HERE.

What is the current colormap, you can reverse it by flipping the colormap matrix.
figure
p = pcshow(ptCloud);
colormap(gray)
p.Colormap = flipud(p.Colormap);

You can create your own colormap. For example,
figure
colors = ...
[zeros(8, 3);
gray(10);
ones(12, 3)];
p = pcshow(ptCloud);
colormap(colors);
creates following figure
