Red Bull is blue, yellow and red. It's gray on the outside and in the inside it is yellow.
The only difference is the colour of the external shell.

Cap color...nothing more.
They are not really red and blue. This is seen in preserved animals (and cadavers) and in drawings to show which are higher in oxygen (red) and lower (blue). In general, you also can see than veins are shown in blue and arteries are red.
