Hi Benjamin,

I'd do something like

h = patch([x3 fliplr(x4)], [y3 fliplr(y4)], 'g' 'EdgeColor','g'); 
set(h,'facecolor',[ 0.5843 0.8157 0.9882])

I got the RGB values of light blue from my rgb function by

rgb('light blue') 
ans =
  0.5843    0.8157    0.9882

Define your colors as 1-by-3 arrays in the range 0-1. For example to have a light blue interior and a purple edge line, do this:

x = [1,4,4,1,1];
y = [2,2,1,1,2];
% Define light blue as whatever values you want 
% but in the range of 0-255 and be sure to divide by 255 to get into the range 0-1.
lightBlue = [91, 207, 244] / 255; 
purple = [103, 2, 94] / 255;
patch(x, y, lightBlue, ...
  'EdgeColor', purple, ...
  'LineWidth', 5)
