It is my understanding that RGB color space is for projected color (created with light--all colors mixed gives white), while CYMK colors are for ink (all colors mixed give black). This is why RGB doesn't always transfer correctly to CMYK.
In other words, and others have said here, what you see on your monitor may not be what you see when you print out the image.
