I'd suggest (but couldn't establish it from literature) that turmeric powder is yellowish ocra in acidic 'solution', because it gives mustard (made with acetic acid) its yellow color, which is not redish-brown like curcuma is in neutral circumstance.
Added:
From one scource it says: ' In acidic solutions (pH <7.4) it turns yellow, whereas in basic (pH > 8.6) solutions it turns bright red.'
