Curator: The decision to restore the cloak of the central figure in Veronese’s painting from its present red to the green found underneath is fully justified.
Background
There's a little Curious Fact / Explanation feel to this one.
Curious Fact: Why is the cape on this painting red on top, but green underneath? (the red paint was added after the painting was completed, and the paint did not come from the artist's workshop.)
Author's Explanation: Someone tampered with Veronese's painting. Veronese wanted it to be green, but this mischief maker added red paint on top.
Art Critic's Response
She impugns the plausibility of the Author's Explanation.
There's a copy of this painting from right after Veronese died. That soon after an artist's death, a copyist wouldn't dream of tinkering with major features of the work, such as the color of this cape.
Evaluate
The critic is supporting the idea that when Veronese died, the cape in the painting was already red. If it had been green, reflecting Veronese's intended color, a copyist working right after Veronese's death would have kept the cape green.
So, if we think that the cape in the painting was read when Veronese died, does that mean that Veronese wanted it to be red? Did he mix some paint at another studio some time after the painting was initially completed, and add that red cape he'd realized he wanted?
Maybe. Could be that some vandal tampered with the painting during Veronese's lifetime, and Veronese was either uninterested in fixing it or unable to fix it.
Goal
Since searching for alternate explanations is inherently speculative, we're probably going to see a correct answer that reinforces the idea that either Veronese added the pigment later in life, or the vandalism happened within his lifetime.
