I am trying to cut/copy a selection from a photo I took of a watercolor, but when i copy it (cmd-c and cmd-shift-c) into a new layer the lighter part in the yellow, pink and green turn really grey. I've tried edit>convert to profile and messed around with that, and I've also tried to make the new documents in CMYK Color and RGB Color. nothing seems to work. I've attached an image of the two documents arranged vertically. the pallet on top is the pasted result and the image on the bottom is the photo I took. I did adjust the image contrast, vibrance and brightness a bit.
Thank you so much.
