Question on warmth/cold on site

MRudland

I calibrate my monitor monthly, but what I am finding is that when I have a "warm" image, and upload it to a gallery, it appears "cooler" than it does on my computer. I have just noticed this in the last 2 months. I need to order a print or two for myself to see the physical difference, but I'm wondering if I am the only one that has had this happen?
Thanks
Michelle

Are you using the sRGB colour space?

Alternatively, are you using a Mac?
