Food and drink colorants.

Disguising a brain burger for a normal burger, making blue waffles, coloring phlogiston in yellow and placing it into the Silver sulfadiazine container! The fun never ends!

You're looking for colorful reagent, friend.

Yep, here is the recipe straight from the Wiki:

Colorful Reagent= Plasma + Radium + Space Drugs + Cryoxadone + Triple Citrus (+ Stabilizing Agent)

It's harmless and colors anything it touches with a random color. Just use it a couple of times until you get the color you want.

I honestly believe that there should be a bottle of colorful reagent placed in the kitchen just like there is a bottle of hairgrownium in the barber's shop.

Now that colorful reagent is no longer secret, I second this.
