I've been helping a friend who's had problems
with the color of her lab's prints of digital images.
To help diagnose the issues, I've added a little
strip of Macbeth color chart hues to several images.
In the strip, the chart colors are repeated three times, against
a near-white, light-gray, and near-black background.
Other folks might find this Macbeth tri-strip image of use. It's parked here:

ps -- The RGB values for the chart come
from Mitch Valburg's excellent 1998 post to
