Do you live close enough to a boutique to try them on? My experience was that the colors looked quite different online than in person. Colors that appear more muted online are actually much brighter and more vibrant in person. I was originally thinking Yves Klein blue, which in person looked almost bright purple. I ended up with midnight, which is thankfully MUCH more vibrant in person and did not much resemble the muted dark navy I saw online.
Wear the colors you normally wear and go try them on. I do not recall seeing the Lady in midnight recently, but I may have missed it. If you wear more teal blues, the turquoise might work. Think about your general skin/hair coloring as well. Not sure how familiar you are with color theory, but People with summer and autumn coloring tend to look and feel better with muted colors. Your discomfort with black and bright red (which are high-contrast Winter colors) might indicate that you belong in the summer or autumn categories, meaning that you might favor bags in muted blue, teal, grey, beige, light pink, soft dusty red, and brown.
Personal anecdote: I always mean to buy beige bags because they are so clean and classic looking, but with my Winter coloring , beige completely washes me out and I end up buying something different after trying it on.
I probably made this more confusing! But bottom line. Try them on in person. It's really the best way to decide.
