Water storage containers

[4kidsmom]

Hi fellow preppers!

I am gearing up to check over our food storage and emergency preparedness stuff.  I want to get some 5 gallon water storage containers.  I have been looking at these two:

http://beprepared.com/aqua-tainer-7-gallon-water-container.html and http://beprepared.com/5-gallon-water-jug.html.  One is blue, one is white.

Is there any difference/advantage/benefit to getting the blue container over the white one?  I'm looking at this website http://www.abowlfulloflemons.net/category/emergency-preparedness and she used the blue containers.
