How can I read RGB values with the EV3 Color Sensor block for Simulink?

I am trying to convert the Mindstorms Rubik's cube solver from NXT to EV3. However, the EV3 color sensor block let's me only read color or reflected light intensity, but not both. The NXT block had RGB output, which is essentially both. It is not possible to change the block from one mode to the other during Simulation. Is there a workaround? Regards, Arne
