Images overlay unwanted colour

Hi there! 

Trying to figure out why the images appear to have a layer of red/pink colour on top of them.

I've tweaked the colours on every setting to try and figure out what was causing that but nothing seems to do the trick. I couldn't find anything on my CSS list either - I deleted everything to see if it would change... 

Please help 😞

The page you shared doesn't exist or is disabled.

Is this a background image or image block? Both have an overlay option in the background or block settings.

Hmm not sure what happened there. 

Here's a comparison of the original image and the one on the website. 

It is an image block in a blog post. I removed all possible settings that I could see in the colour editing section... Not sure what else could be causing this, but it's on every image..

I can only see a colour-cast on certain images, and when I look at the uploaded image via the base code, it has the same colour-cast.
