How to repair locked profiles of coloursyn utility?

I was using my macbook air on routine basis that suddenly a layer of distorted colour appeared. Then i went to the colorsync utility and found six errors. i tried to fix them many times but unsuccessful. These profiles were locked. but i tried to find them in finder by

1. pressing shift+cmg+g

2.then pasting in go to finder.

3.then opening "get info".

4. then i tried my best to change the privilege of every one to read and write so that the profile may be unlocked and repaired but get the error that i don't have permission to do this. ?

Please help me
