Color introduces HUGE problems _IF_ you are concerned about 100% accurate color reproduction on any output "device".

IF AND ONLY IF they are authored properly, incorporated into color-aware file formats, and then viewed/displayed/printed properly.

Otherwise, nothing works 100% correctly.

Of course, in many cases, you may not care if your "red line" is a bit darker or lighter as long as it is "red".   But if it were to turn "green", then you might care!

Actually many devices are even worse (when it comes to handling color properly), as they don't bother to include and/or support color management.  In fact, the ICC (International Color Consortium) has decided to focus a big part of this years "DevCon" (<http://www.color.org/DevCon/devcon12.xalter>) on the areas of mobile and web color management.
