Is there a capability.rgb or similar for color-changing devices?

I would like to write an SmartApp for a custom arduino device type I have created that changes color based on the weather forecast. I would like this app to also work for hue lights and lifx. Is there a capability.rgb or similar I can use to allow users to pick any of these device types in my SmartApp? How would I go about registering my Device Type as having this “capability”?
