The context makes it different then what you claim. As it is talking about the ingots and rings being a different combination of two colors. Which is a factual thing that isn't linked to ratios discussion at all. Nor does it say that the color change happened because they decided to make rings. You conflated two different statements into one concept. I only called it a continuity goof.
You also ignore the context because it was you making the argument that the magical properties of Mithril causes color changes to happen when shaping it into objects. It is strange how you assign that argument to me when it is one you created. Lmao.
