URP Lit 2D Sprite Shader Texture

Hi,

I have a texture on a sprite, but I need to change the red on the texure to a given colour (from shader property) and apply it to the sprite. For example, if I just had a red circle, I would want my shader to display that red circle but in the colour that I chose in the inspector.

That being said, I can't seem to figure out how to split colours from the texture... I want to override the red channel to something else, but I don't know how to do so.

I'm not new to shader graph, but I usually stick to HDRP and 3D, so lit 2D URP shaders are alien to me.

Here is what I have so far:

Looking forward to hearing back from someone and thanks dearly for your help, Ethan.
