Apologies if this has been addressed elsewhere but I wasn't able to find a solution. I'm opening a number of images in Photo and Designer and finding the colours to be less saturated than the same images in OS X Preview and Photoshop. I've checked, obviously, and the colour format is RGB, not CMYK.
I've attached the original and a comparison showing Preview, Photoshop, and Photo. You'll see the first two images look nice and saturated, however the last one, in Photo, looks washed out.
