ComponentParam.getColorValue() throws an error instead of returning 0 when unsuccessful

I'm iterating through the properties of a component in Premiere Pro using ExtendScript. In order to detect whether a property is a color value, I'm calling getColorValue() as suggested in the documentation.

According to the documentation, this method is supposed to return 0 if the property is not a color. However, in practice, it throws an "Unknown error" exception when used on non-color properties.

This makes it difficult to safely check if a property holds a color value, and it contradicts the behavior described in the documentation.

Please clarify if this behavior is expected, and if not, consider updating either the documentation or the method implementation to align with the documented behavior.
