I've been working with changing Blending modes for overlays in styles, and thought you might get a kick out of this as well. The technique is simple, but the effects they produce can be quite striking.
Just for kicks (and to once again go through the process of creating a style) let's start applying layer effects to some type. You know how I love type.

Let's start with a Bevel:

Let's add a little Satin:

Apply a pattern of your choice, as well as a drop shadow. Here's my image thus far:

For the last couple additions, I've applied a slight outer glow and just a touch of inner glow. The inner shadow for this one really makes the image stand out, so the settings here are as follows:

Ok, now the image is set up just about where I want it. What I'm doing next is applying a color overlay and changing the blending modes to let you see the difference. In working with these you can squeeze double, triple or more effects from a single layer style, just by fiddling with a color or gradient overlay blending mode. I'm working solely with RED just to demonstrate the power of a single hue variation. Here's are my examples:
NORMAL Mode:

MULTIPLY Mode:

SCREEN MODE:

OVERLAY Mode:

DIFFERENCE Mode:

SATURATION Mode:

LUMINOCITY Mode: Opacity set to 40%:

Try going through some of your favorite layer styles and tweaking the overlay blending modes.
