Set facecolor in app designer

I have a circle in AppDesigner with different segments and I want to set the color of each segment individually. When I use the code below I get an error:
"Error using matlab.ui.control.UIAxes/set. Invalid parameter/value pair arguments."
However the same approch (without the app.UIAxes handle) works as expected in a normal script. Can someone point out to me where I might be going wrong?
x0=0;
r=10;
y0=0;
t1 = linspace(0,pi);
t2 = linspace(pi,2*pi);
x1 = x0 + r*cos(t1);
y1 = y0 + r*sin(t1);
x2 = x0 + r*cos(t2);
y2 = y0 + r*sin(t2);
pie=fill(app.UIAxes,[x0,x1,x0],[y0,y1,y0],'w-',...
[x0,x2,x0],[y0,y2,y0],'w-');
axis(app.UIAxes, 'equal');
box(app.UIAxes, 'off');
axis(app.UIAxes,'off');
set(app.UIAxes,pie(1),'facecolor',[255 85 180]./255);
set(app.UIAxes,pie(2),'facecolor',[255 0 0]./255);

No need to pass app.UIAxes in these lines
set(pie(1),'facecolor',[255 85 180]./255);
set(pie(2),'facecolor',[255 0 0]./255);

I am glad to be of help!
The first input to set() is the handle of the graphic object you are trying to modify. You already have handles to patches. You don't need anything else.
