Well, almost. First, there's class. Lots and lots of tedious class.
Color AND size coded?!? Oh, Hank, you were tightly strung weren't you?
Still, looking at the convenient projected chart, you can see that some of the capsules are intended to increase your size, and some to decrease it. Or, to put it in 1960s psychedelic terms...
One pill makes you larger
And one pill makes you small
And the ones Reed Richards gives you
Don't do anything at all
Go ask Hank Pym, when he's ten feet tall
And if you go chasing villains
And you know you're going to fall
Tell 'em a genocidal Ultron
Has given you the call
To call Hank Pym, when he was just small
When the men on the Avengers get up
And tell you where to go
And you've just had some Pym Particles
And your mind is moving low
Go ask Hank Pym, I think he'll know
When logic and proportion have fallen sloppy dead
And the Vision is talking backwards
And Bill Foster's lost his head
Remember what the Skrull Queen said
"Janet's dead, Janet's dead!"
