My macbook pro screen keeps turning blue?

This just started about ten minutes ago but its happened three times so I'm kind of concerned. My screen background on my Macbook Pro turned blue after I refreshed a Netflix page. None of my open windows shut down but the image I have as my background was gone and the light blue screen took its place. When I went back into my settings to put the picture back up, it showed that it was still set as my desktop screen, even though it clearly was not. I had to click on another image and then click back on the one I wanted to get it to reset. Is there any reason why this is happening? And can I fix it or do I have to take it in to the apple store and see if they can take a look at it?
