Unity Shader Graph Transparency Issue

Hello! I am using the Shader Graph to make a Portal Material for my project. However, when use a multiply node to add a color, like Bright Blue, to the Shader and plug it into the Emission node, nothing shows up in my preview or in my scene. But if I have a color like Red, it does show up in my preview, but still nothing shows up in the scene. Here are a couple of screenshots:

I think it has something to do with an alpha setting SOMEWHERE. Not sure though.

The issue was resolved. The tutorial I am following is using Unity 2018 and I am using 2019. Shader Graph back then allowed colors to be recognized in the alpha channel but in 2019 they don’t. I had to feed the color into the albedo separately from the mask.
