randomize the hue of a sprite

[Cruelty]

might somebody be able to help me with a script to randomize the hue of a sprite?

to be more specific, i don't want to just randomize the hue of just any old sprite, but rather i'd like a script that could be applied to whatever event happens to be 'active' at the time (the same exact way you can select 'this event' under the 'set move route option'), and effectively set it's hue randomly.

thanks in advance tho whoever may be able to help me out here!

edit; I am using RMXP
