Wiz - Please explain how A and B are the same color. B is in shadow and appears lighter in color than A which is not in shadow. What kind of optical illusion can do this?

8725. TheWizardOfWhimsy - 12/10/2008 4:50:55 PM

The optical illusion comes about through what is called simultaneous contrast of light and dark. (The light or dark, some times termed brightness, is called "value.") So you need to see it in terms of "value" not "color." The cast shadow from the green cylinder darkens all of the squares and the darker squares adjacent to "B" make it seem lighter--however it is the exact same value as "A" but because "A" is adjacent to lighter squares and the white background, "A" seems much lighter by contrast.

Here is a less confusing example that uses the same contrast principle. Note how the values change on the dots when you look at it directly and indirectly. The cones in you eyes are fooled because they work by means of contrasting light.



This one uses color and both center squares are the exact same value, but note how they appear darker or lighter because of the adjacent color field that surrounds them.

Wiz, I did not believe they were the same shade. I would have bet 10 dollars against it. Just for kicks, I copied and pasted a bit of each square in PS and compared the shades. I would have lost 10 dollars.

It makes you wonder about the many illusions in existence that we never question.

As a wise man once said, anomie:

Life is a journey from the illusions of certainty to the certainty of illusions.

Indeed, the older I get, the less I know, and the wiser I am for it. For instance, ten dollars wasn't much to wager. Ha!

A good ethical man!

Indeed. I'm sorry there aren't more clips from The Servant on You Tube. Pinter appears in the famous restaurant scene and his line deliver is the epitome of razor-sharp elegant wit.

Orson Welles called her "The most xciting woman in the world."

Here's a clip of her in All By Myself -- a marvelous documentary portrait by Christian Blackwood made a number of years back.

Harold Pinter is dead


A presence who had accompanied me throughout my adult life.
His Nobel acceptance speech from 2005 bears re-reading.

The country would benefit if there were more "blended families."

Yesterday I saw the “Titian, Tintoretto, Veronese: Rivals in Renaissance Venice” at the Boston Museum of Fine Arts. If you get the chance to see this show, do not miss it — Holland Cotter fears there may not be many more big art shows for a while. I don't have a lot to add to his review.

The show is hung by subject, not by date, and similar works are side-by-side or very close to each other, allowing the viewer to see the similarities and the differences. Many of the Tintorettos in particular stand out, because he used very heavy shadowing, almost outlining his subjects. However, not all his paintings are so obviously different from Titian and Veronese; some are similar in their technical execution, though his compositions are his own, full of diagonals and action. He seems to have been the wild man of the three.

Veronese was the quieter, gentler prodigy, taken under Titian's wing. Titian and Tintoretto had a true rivalry, but Veronese was more amenable and seemed less threatening to Titian, though Veronese's talent was unquestionably great.

Titians colors are luminous, especially his reds, and the visibility of brush strokes in his later works is so different from the invisible marks in the early work. In one painting, The Supper at Emmaus, the detail on the tablecloth is amazing — not the folds, but the actual pattern of the cloth. You need to be fairly close to even notice it. I'm not a fan of fussiness, but this doesn't seem fussy, it is part of the completeness and tranquility of the painting. The Tintoretto of the same title next to it seems harsh and violent by comparison.

An interesting part of the exhibit involves the restoration of Tintoretto’s Nativity. The painting is in a small, darkened room, along with x-ray images of the underpainting and speculation on what that painting was, why that particular canvas was reused, how the Nativity painting was made and changed, and more. A film crew was there, so something may show up on tv about this painting and what is being revealed by conservation science.

It's a wonderful show, made up almost exclusively of Titians, Tintorettos and Veroneses. The single Bellini at the start of the show is meant to illustrate the move from painting on wood panels to painting on canvas, which allowed painters to paint larger works and not have to paint on site. It's hard to pick a favorite room, but the portrait room is stunning.
