flush & blush[edit]

The fact that flush and blush share a meaning “turn red in embarrassment from flow of blood to face” and sounds very similar is interesting, but AFAICT these words are completely unrelated, as etymologies indicate. It’s conceivable that blush (older term in this sense) influenced the “turn red” sense of flush, apparently from 1620s, but that seems a stretch.
