Make Glow different than "inner" Material

I’m a pretty noob when it comes to creating materials and such so my question is how I can make a glowing ball in which the glow is a different color than the ball itself.

To visualize:

This is what I have

(its kind of glowing more in the editor my ss tools are bad)

.

This is what I want

I want the ball itself to be red but the glow should be blue

Is there any way I can achieve this inside the Material

This is what my material looks like right now

You can use a Fresnel-node as an Alpha for a Lerp-node between inner and outer colour. The effect gets stronger if you increase the Fresnel’s exponent-variable.
