1) When I am copying a logotype from one Illustrator document to another the colours are changing slightly. Anybody know why this could be?

I am noticing that the CMYK values are also changing, so it is not only how it looks like. The "old" document is created in cs5 and I am now working in cs6. Maybe it could have to do with this? How do I fix it?

2) I have the Pantone values written down for the colours of the logotype. When I put the same Pantone colour in the "new" document it becomes a different colour again (the same as when I dragged the logo into the new document). It is not the same! why? I need to be able to tell clients what are the Pantone colours of the logotype, so this is a huge problem..

I am very thankful if somebody can help me with this!

screenshot your color, then open it in Illustrator and eyedrop it. it's just a quick fix but it works. –  user24705 Jun 6 at 18:12

1) Illustrator CS5 and CS6 must have the same color settings (Edit > Color Settings) for CMYK values to be the same. If you have mis-matched color settings, values will change.

2) Regarding Pantone colors, there is a marked difference between CS5 and CS6. CS6 uses the new Pantone Plus libraries which are built only on LAB values. Previous Pantone libraries were built on CMYK and LAB values. Check Adobe help pages for solutions to the pantone color issues. http://helpx.adobe.com/x-productkb/multi/pantone-colors-dont-match-illustrator.html Although it is best to adapt to the Pantone Plus libraries if possible. The difference won't effect printing, but it will alter the on-screen appearance.

1) yes this answer I have already seen on other pages. They are both the same, I have checked. But the problem is still the same. 2) Ok thank you I will check this. Although I have read that it should look "right" after choosing view-overprint preview. But for me the colour is still wrong. Could this mean it is not fixed and will not look "right" when printed? –  Sara Shellhammer Jul 17 '13 at 16:02
    
If your color settings are the same between CS5 and CS6.... and you are working in CMYK or RGB documents in both versions you should not be seeing a color shift for those color profiles. And please READ the Adobe help page I linked to before trying to explore the Pantone issue more. –  Scott Jul 17 '13 at 16:04
    
Thank you. I have read it, and it definately helped me understand pantone colors better. Although it did not help me understand how to make it the same colour in my documents. Although choosing the same pantone colour I get completely different cmyk values and it does not look like the same colour. –  Sara Shellhammer Jul 17 '13 at 16:20
    
Perhaps you should read again. The new Pantone libraries are NOT built on CMYK values. They have no inherent CMYK values. And because they are new libraries, they will have different CMYk breakouts. Why would you worry about that? Pantone colors aren't meant to replace CMYK colors. And traditionally pantone CMYK breakouts change with every new Pantone release. –  Scott Jul 17 '13 at 16:23
    
Ok, so it has nothing to do with the CMYK values. But the problem is mainly that is not at all the same colour to the eye, and it should be. How would I then get the exact same colour. I have to find a new pantone color that looks the same? Sorry, but I am new to this. –  Sara Shellhammer Jul 17 '13 at 16:26
