If you hold one of the following items
any spawn egg
enchanted books
golden enchanted apple
nether star
grass, leaves any of these
the next thing happens:
you have an empty inventory -> take 1 of the items
your xp-bar will change color depending on which item you had.
if you add 1 of the same item the xp bar will turn back to normal having it green.
Check the screenshots for black and red xp-bars.

The first image is a chicken spawn egg that turns the xp bar into red
the second one is a creeper spawn egg (also works with an enderman spawn egg) which turns the xp bar into black
the last two are actualy 1a and 1b. 1a is just one golden enchanted apple. 1b is a stack.
