I get what you mean.
Personally I interpreted it as representation of pathological blushing.
I blush at almost anything. It's really annoying. So I didn't notice Lucia doing it. It can be as Lady Nd9 stated.
Um..am I the only one who cringe everytime I see Lucia blush? Don't get me wrong, I know blushing can make characters look very adorable, but I think the art needs to chill a little. I love the appearance of Lucia, heck she is such a beauty and cute at the same time, but the frequency of her blushing is just a bit too much for me. What makes me cringe even more is every time she blushes so bad to the point her skin tone looks like boiled crab (exaggeratingly red!!) over things that shouldn't necessarily make her blush that bad. I still like seeing her blush tho, but I hope they tune down the coloring and its frequency a bit.
