Website uploads look washed out
Hi,
I'm having an issue uploading a Photoshop illustration to a Squarespace website. I am exporting a jpeg with sRGB profile, which looks fine in the Windows picture viewer. But when I upload it to a Squarespace website, the colours look washed out. I have not had this issue before so I am not sure what I am doing wrong and whether I have an export setting wrong, or whether it is an issues with Squarespace. Also, I always use the 'save for web' option from habit. I don't know if this makes a difference, but as I say, I have never noticed an issue before.
I have tried viewing in both Chrome and Edge but with the same result. I have attached a screenshot below. The left image is Windows picture viewer, while the right is Squarespace.
Thanks for any suggestions.
