Choosy Collectors

Seems the museum is holding a private auction for some rather picky buyers.

It might be a bit tricky, but it's probably possible to figure out, for each piece, who'll be a “yes” and who'll be a “no”.

If a buyer's ever caught between two pieces, they just have to ask themselves…

Buyer 1: "I aim for a wide palette of art to display!"
Samples from their collection: Seeing Red, Blue Skies, Sun Tan, and Silver Linings

Buyer 2: "I find the theme of repetition fascinating."
Samples from their collection: Spoons, The Lonely Bookkeeper, Broken Boombox, and What a Mess

Buyer 3: "Well to start, there are five - sometimes six - qualities that make a good painting"
Samples from their collection: Amazement, Under Water, Inch by Inch, and Eden

Buyer 4: "A Q and A? Hm... I'm half interested..."
Samples from their collection: Praise Quetzalcoatl, Queer Joy, Equine Show, and Inquisition

Buyer 5: "Don't take my word for it, I've gotta have more than one!"
Samples from their collection: Final Work, The Meaning of Life, Once Upon a Time, and Welcome Home
