need to see all of their images in device-independent accuracy. You
don't even need to buy special hardware. This weekend, pull up a
monitor and see what all the technicolor fuss is about.
"I'll be the first to admit that I write about color management
more than the average Linux user cares to hear about it. I mention
it whenever I review graphics apps for two reasons: first, because
it is a must-have feature for photography and graphic design, and
second, because desktop Linux is right on the verge of making it
simple and ubiquitous, which will be a major win. But it is not

"For those totally new to the subject, the essence of color

but because all digital colors are nothing more than numbers (think
RGB triples...), we can mathematically convert each number so that

monitor — what part of the the 3D color space it can actually
