I opened a new document and using cmyk setting with profile U.S web coated. All the colour changed when I saved it to jpg, what should I do?

lol.. i guess i start to understand a little bit adi.

The adobe photoshop in my com is using profile: U.S web coated mode for CMYK. When i view it in acd see the colour change, i can't see the exact colour for my work. I wonder how to change it? I don't know how to set the preference in the acdsee there to match my original work, but when i'm using the window fax and preview program which included in winXP it turn out to be the original colour i used in my work.

Jayhan, i preview it using lousy (but very handy) window fax and preview but it showed the original colour... but it's different in acdsee...

and yaya, i started my work in cmyk...
