Change Background colour between values

Hello everyone.

I'm building a script that follows the angle of a IMU (Inertial Measurement Unit) in real time.

In this script im using a GUI, which shows the angle in numbers on a big "edit text" field with a white background.

(gui looks like this):

I want this background to change to a green color when the value of the angle is between 14.1 and 14.9 and between 19.6 and 20.4.

if the value is outside the given values the background should have a red color.

right now, this is what my script looks like:

function pitchTB_CreateFcn(hObject, eventdata, handles)

if ispc && isequal(get(hObject,'BackgroundColor'), get(0,'defaultUicontrolBackgroundColor'))
    set(hObject,'BackgroundColor','white');
    
    Data = handles.pitchTB;
    if Data(Data > 12.1 && Data < 12.9)
        set(hObject,'BackgroundColor','green')
    elseif Data(Data > 19.6 && Data < 20.4)
        set(hObject,'BackgroundColor','green')
    else
        set(hObject,'BackgroundColor','red')
    end
    

The code doesnt give me any errors, but it wont change the color of the background.

Does anyone know what im doing wrong?

Found the problem. i was working in the create function, which means the script doesnt get updated while running the GUI.

i put it underneath the timer function, which led to the script working:

  if (eulP < -12.1 && eulP > -12.9) || (eulP < -19.6 && eulP > -20.4)
        set(handles.pitchTB,'BackgroundColor','green');
    elseif eulP > -0.10 && eulP < 0.10
        set(handles.pitchTB,'BackgroundColor','white');
    else
        set(handles.pitchTB,'BackgroundColor','red');
    end
