The veneer on this table is all of the same wood. The pieces where the
grain is running parallel to the line of view appear darker than those
where the grain runs perpendicular to the line of view.

What is this effect called?

Obviously, the grain is oriented in such a way that it reflects light
differently from different angles. If there is a name for this, I don;t
know it. Maybe we can make one up. How about differential refraction? :-)

On second thought...a little google research reveals that the proper
term for this effect is "iridescence".

I enclose a paragraph of terminology concerning veneer.
GLOSSARY OF VENEER MATCHING TERMS:
Matching Between Adjacent Veneer Leaves
Book Match - Matching between adjacent leaves of veneer on one panel face.
Every other leaf of veneer is turned over, so that adjacent leaves are
"opened" as two pages of a book. The fibers of wood, slanting in opposite
directions in the adjacent leaves, create a characteristic light, dark when
the surface is seen from an angle.
Slip Match - Matching between adjacent leaves on one panel face. Adjoining
leaves are slipped out in sequence, with all the same face side being
exposed.
Swing Match - Matching between adjacent leaves on one panel face. Every
other leaf of veneer is slipped and spun 180 degrees.
Random Match - Matching between adjacent leaves on one panel face. Random
selection in arrangement of veneer leaves from one or more flitches
producing a deliberate mismatch between the pieces of veneer

I've always heard it referred to as chatoyance.

P.S. Nice table.

I like the term "differential refraction" better! GRIN!

the wood was cut quartersawn, which makes the grain reflective like
fish scales.
with only one light source it hits the wood from only one direction
and creates the effect.
i don't know if it has a name, ask a photographer

It is called 'stripey grain', caused by trees that grow the grain in spiral
fashion, changing direction each year.

Thanks, guys.

Chatoyance wins the votes and it's the term I'll use.
