Message Equivalent of TextChanged for Graphics?

[Scott Rossi]

LC now has a textChanged message that gets sent when text in a field is
changed by the user.

Is there an equivalent message for when a the fill or color of a graphic has
been changed?  Or is the only option to run a looping script that checks for
changes in visual properties?

Thanks & Regards,
