Eat Mars Candies and lose weight!

These are the stupid things you do when sitting in a hotel room trying to pass time. You read the back of the MnM packet and start blogging. Interestingly enough Mars claims the color distribution in my packet is

Brown: 16.6%
Yellow: 16.6%
Red: 16.6%
Blue: 16.6%
Green: 16.6%
Orange: 16.6%
Invisible: 0.4%

So let's see, if there are 250 calories in each serving and there is one serving in a packet then I actually save about 1 calorie due to invisible MnMs. I wonder where they buy the invisible color and how do they know they actually get in the packet? How does one do quality control on invisible items?

For example, how does Wonder Woman know if someone stole here invisible jet? Are her keys invisible too? That would be a bitch if she lost them. Makes a good case for a clapper unit. I can hear it now;

WW: "Honey, have you seen my keys for the jet?"
Husband: "Ah.....No?"
