Hey
At first I was of course once again blind an didn't see the changes. Then I noticed
what you have done. I love it! We're getting somewhere
This is the first one
I've seen that has replaced several images.
Now I can imagine two versions. Either go with the flow and take colours that
are present in the images. I can imagine a creamy light blue and/or yellow.
Another idea would be to create a contrast so that the images stand out more.
I'd do so by darkening the frame.
Mayhap it does look better in my head than it does on screen, but if you have
the time and motivation and don't think it sucks completely, try it out
