How Do I Get Pixel Color That Includes The SpriteRenderer Color Change?

Hello, I have two images I'm using as sprites. I'm trying to read them both and write them combined as a third image which I'm using as a third sprite (seen in picture). I would like to be able to write using the color change I make in the sprite renderers of the original two images (currently only applied to the first sprite). Currently it is not including the color change when writing and is just creating the 3rd image based off of the original colors of the first two images. Is there a way to do this or some code to do the same thing that the color sliders do to the original colors of a sprite?

Does anyone know how to do this?

Thanks for your help.
