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

Thanks for any help in advance

Basically you need to use a Fresnel node to keep one color at the edges while the other is in the centre.

Not at a machine at the mo, so can’t demonstrate, but this might help:
