Colour suddenly changed in InDesign
I've just opened a doc in indesign that i was working on last week and i have found a number of the colours are now muted. I was using a blue at 20% which looked fine last week but this week it appears to not be there at all. I first checked my computer's display settings but everything is as it should be. This seems to just be an issue with Indesign as I have pdf'd the doc and viewed it in acrobat on the same computer and the blue is visible. I've also checked the original file on another mac through indesign and the blue is very much still there, the doc looks just as it did on my machine originally.
Is there an Indesign keyboard shortcut i have accidently pressed to have caused this. Does anyone have any ideas?
