Ode to an M&M

Red orange yellow, green blue brown.
But on holidays, rare colors are found.
Even though you all possess the same flavor,
Red is still the color I favor.
And for some reason, all of the reds are passed
so that I can eat my favorite last.
And, Orange, I dislike you the most.
You taste no different, but have nothing to boast.
So, of course, I eat you first.
You're not bad, you're just the worst.
To this I bet we can all confess.
It's just a sort of tradition I guess...
