But it won't let you change the color
look for this line in outline.fx
if (left.a != 0 || right.a != 0 || top.a != 0 || bottom.a != 0) {
return float4(1,1,1,1);[/code:gzfu65zr]
replace the first three values of float4(1,1,1,1) with your choice as a percentage. They represent the r, g, and b values (the last one is the alpha value). if you are used to working with values 0-255, devide by 255.
