The Leo Quartet (しし座の4つ子) NGC3190,3193,3187,3185

After three years, I finally got the shape of each galaxy.
I proceeded with the editing with the colors that were calibrated with SPCC, but I wondered if it was really this blue.
I did an image search and looked at various things, but it was blue or brown. It was pink for some reason.
