I don't know about you, but I am a nut about color.
Sometimes I want and need accurate color, as when I was working with the scientists on my butterfly book, Flying Flowers - which I turned into an app called Butterfly Wonders.
At other times I want more vivid color, as when I am working on a travel photography piece that includes several sunset pictures.
Here is a link to an article I wrote on getting Knockout Color.
And here is a link to an article (much more technical than mine) on color management by my friend, the King of Color Management, Eddie Tapp.
For those times when accurate color is a must, I use the colorchecker Passport from x-rite. Here's how it works: You take a picture (RAW of course) of the 24-patch Passport, load the included camera calibration software CD on your computer, open your target image in the program, makes a few clicks of your mouse (or taps of your stylus) - and you are on your way to accurate color. Actually, you were on your way to accurate color before sitting down at your computer. :-)
Enjoy your journey and explorations into the world color.

P.S. As long as I am talking about passports, when I travel internationally, I pack a copy of my passport in my checked bags and in my camera bag (s). That way, if I lose my passport, I have a backup I can take to an embassy. Also, if my bags are checked by airport security, the agents can ID me quickly.
