Color Palette as caption or text

Dear all,

In my job I often create some guidelines for various companies.

My problem is, each time I create a colour palette for them, I have to write the colour codes in RGB / CMYK / # (and sometimes Pantone®)

Is there an automatic way to do that ? A script maybe, that produce text code of the colours, then I just have to copy-paste them in my document....?

Thanks in advance for a tip or the solution

Michel
