This song is about not being able to open up because of insecurities. She used a few metaphors to get the point across. Grey is used as a representative of the space between the night (black, darkness) and the day (white, light) Those two colors mixed or as it relates to the mood of the song are meshed together, which form gray.

@neversaycant1 Actually you are way off as Natalie has stated the meaning of this song in several interviews and the meaning once explained is very obvious. The meaning for example is knowing what is right and not acting upon it ( she also said it applied to know the right thing to say and not saying it) and then later when you are alone say at night in your home thinking "I knew what was right when I saw what was wrong and did nothing, and regretting it. The grey is the grey area of indifference." These are Natalies words,...
