Does anyone have some sample code or can point me to the ArcObjects needed for adding a new value to a unique value renderer?

I have a layer displaying with a categorized unique value and I would like to programmatically add new values to the list as they are created. I'd like the new values to use a random color from the same color ramp being used by the existing list of unique values.
