How can i create a colour in blueprints for a material in Unreal which consists of 2 colours that create a gradient?

Hey everyone,

I appreciate you taking the time to read this and or help me out ?

Looking for a little help with blueprints in the material editor. I am trying to make a custom diamond like material and took some of the blueprint setups from other materials which are not custom. As the question in the title says, i want to make a colour in a 4Vector/ColourParam which consists of 2 colours. The picture below will show you better what i mean.

I simply want to be able to create a custom gradient of 2 colours like the red arrow points to, if i change the "Value" of the current 2Colour Gradient that i have it disables this gradient effect. Can someone help me please? ?
