Ah, OK. I think you will find that the yellow filter will lighten both the yellow slicker and the orange hat, as both contain yellow. It might lighten the slicker slightly more, however. So, you might try one shot straight, and one with the filter, to be able to compare the degree of separation.

I've often thought that large patches of velcro and super-glue would work wonders when shooting kids, but it's tough to get the mothers to warm up to the idea.
