    I'm completely new to Shader Graph and was wondering if its possible to replace/swap a particular color...
    like Green (0,1,0) from a color property in Shader Graph. Thanks in advance!

    Yes there is. Just type in REPLACE keyword in the search field, when placing new node.

    I was using a Replace Color option in Shader Graph but the problem why it wasn't working for me is my range wasn't high enough. Even though the color is exactly Green (0,1,0) on the texture, I still needed a range.

    Still learning... I'm trying to replace multiple colors of a 2D texture. I'm using a Color Mask then using a Replace Color. Now I'm not sure how to apply the updates to the 2D texture. Any advice for this?

    Not sure if it's the "right" way, but I used a Blend with a Screen mode to combine them.

    In this case you get the same result by just simply multiplying the individual channels of the texture with a color and than use the blend function right?
