For the Color challenge - started with 2 large photos - my ocean scene on the right, a new mural in town on the left.
Used Scenic Template Album 10 page 18 (in Overlay Mode over ArtPlay Jollification papers and Transfers) to blend the ocean photo, with 2 more copies above it - Normal, then 2 Overlay, allowing the 2nd Overlay copy to extend over the mural photo.
The mural photo ended abruptly at the roof of the building, so I added dimensional flowers to complete it. Mural is in normal mode with a mask and erasers to blend it.
Clipped the mural credit and 2 ocean photos to the frames, changing their sizes.
Built a title cluster.
Used 2 copies of the swatch - can you find them? One is obvious, the second it blended ;-)
To balance the visual weight, I added sprinklez on the right.
