I have uploaded my vector images to numerous platforms including Instagram, Pinterest, Shutterstock, Creative Market, Tumblr, etc. The color always stays true to my original.
For some reason, when Adobe Stock creates thumbnails of my images, the color saturation gets uniquely cranked up. A subtle gray-green can turn into a bright, gaudy kelly green. A nuanced red becomes an oppressive hot pink, etc.
I spend a lot of time fine-tuning my color schemes to be lovely and harmonious. It's a bit soul crushing to see such a dramatic conversion. I upload in RGB. Does anyone know if uploading CMYK files circumvents this problem? Any other solutions?
