A red in painting is really a red paint something material. In photography is just an element of reality
I think you're confusing the material artifact of an artwork with the subject matter it may or may not represent, and disregard or are unaware of the fact that no literal subject matter may exist, or that whatever aspect of reality was depicted no longer literally is the subject matter of the resulting artwork. As to the latter, you seem to accept that this is the case with paintings (at least, that's what I suspect), but not with photographs. This sort of inconsistency is puzzling to me, but in earlier instances where attempts were made to make you realize this, any counter-example was shot down as just not good photography anyway. Ah well..
Then that statement of how color cannot be a "transformative building block" - what's that anyway, a 'transformative building block'? Color sure as heck is a main building block of many images or artworks (photographic or otherwise). As to being 'transformative' - color can either be manipulated or twisted to a great extent (counter to your statement in post #1, which lacked any clear basis and seemed just, well, incorrect to me), and in a figurative sense, it can be such a dominant aspect that it 'transforms' whatever reality was photographed by attributing or emphasizing an emotion or a meaning that was lacking in the original scene.
But really can you remind me what are we really arguing about?
The kind of normative statements that are interspersed with your apparent/indicated desire to learn something, such as the two I highlighted above (and many others). Those two aspects (learning and being normative) seem at odds with each other. You're either strongly normative, in which case there may be a willingness to learn, but no ability, because your norms stand in the way of changing your views. Or you're out to learn something, in which case you'll have to let go of the normative stance. I'm normative in the sense that I believe that 'anything goes' (cf Feyerabend), but to make that possible on a forum, there needs to be space for all voices to be heard. If one voice is consistently and strongly normative, then that voice can expect fierce resistance from my end. Basically, if you want to believe that there's such a thing as good or bad photography, be my guest. Same for preferring color over B&W or vice versa, film or digital, etc. etc. It's all good. But the moment someone starts down the path of "color cannot make good art" - well, not in here, you don't. Find a different bar for that brawl.
