Blue life purity and health bars

Today is the color blue, have you ever noticed blue is used over and over again in some of those old religious paintings especially on Mary. Well after I got done watching too much history channel I decided to go and look up exactly why the artists did that. What I found out is that Blue represents water, like we all didn’t already know that, but the fact that it represents water also makes it represent purity and life. So now this is starting to make more sense since Mary is supposed to be a symbol of purity she’s frequently dressed in blue. I also took the liberty to find out if anyone who wasn’t a renaissance painter also used blue for its representation of purity and life. Well go figure game designers have used this several times. An example of this is look at some games “Life Bars” they’re either green or BLUE. So next times you decide to acutely use that neglected blue ink pen of yours remember your writing purity… well I guess it depends on what you’re writing but hey it’s the thought that counts.
