change a logo to specific cmyk values

Hi, I am having troble converting a logo in a PDF to specific CMYK values (the logo top left on the example). Its a slight change to lighten the colour. I've been able to convert the other text on the page, but not the logo. I'm using latest version of Acrobat Pro and Pitstop, but I'm not an expert on them. I've tried every avenue I know, and explored some i didnt know, but no joy. Any advice would be appreciated.

Just to let anyone know who had a similar issue, I managed to figure out a way. In Pitstop Inspect I was able to select the object and in Inspector under actions, I converted it to a spot colour. Then in Acrobat Preflight i chose 'map spot colour with specified name and colour values' where I could give the spot colour name, and provide the CMYK values to change it to. There may be another way, but this was the only way I managed to get working. I think the reason this worked, is that when i used the eyedropper, the logo and slight colour value variations over different areas, and even when I tried using colour range option ni Pitstop, it just wouldn't work, but using the spot colour option did. Hope it helps anyone else with the same query.
