What is this material node?

I’m newer to the material/texturing side of Unreal Engine so I decided to get some help:
[Tutorial][1]

Although I need to add a node and I’m not so sure what it is:

Any help would be great as this is new for me.

this seems to be a scalar hold the key “1” and click in the graph, so a scalar value will appear with the value of 0, it’s basically a float, if you click in this arrow (in the top-right corner) it will open the box and you will be able to see a “color” (this is not a vector so the color goes basically from black (0) to white(1) through grey) you can then change the value to 0.03

the only thing that makes me have a doubt is because it’s color is black, and usually it’s green+black, but try it.

Thanks! It works.
