Happy New Year! Please update EveryCircuit to version 2.27 to get RGB LED. Its package contains three internal LEDs in a common cathode configuration. You would typically use three separate current-limiting resistors connected to the anodes.
It may be tempting to use just one limiting resistor connected to the cathode, but you will find it difficult to control the color. E.g., increasing the red voltage will increase the cathode current and voltage drop across the resistor, which in turn would reduce voltage drops across green and blue LEDs. Try this out for yourself.
Typically the red LED needs smaller forward voltage (around 2 V) than green and blue (around 3.2 V). To get started, the RGB LED in this example is configured for the same forward voltage for all three internal LEDs.
Another new feature in 2.27 is RMS measurement. It is displayed for periodic waveforms under the oscilloscope. On mobile, the What's New screen has a link to the Gallery of 100,000 circuits published by the Community, https://everycircuit.com/gallery. Clicking on a Gallery circuit will open it inside the app.
