Color Changing Sidewalk Chalk

Summer days are almost upon us and warm sunny days always remind me of colorful drawings on the sidewalk. This year we got an early start and have so far made quite a few cute kids drawings, but this time around with a little twist! ๐Ÿ˜‰

We used chalks I made with the help of my little girl. And this chalk changes color while you draw, so our drawings are especially colorful this year!

Color Changing Sidewalk Chalk

To make homemade color changing sidewalk chalk you only need three ingredients and plastic or silicone ice cube trays.

*The ice cube trays are not going to be suitable to prepare ice afterwards so keep that in mind. You can of course use them for other artistic projects.

YOU’LL NEED (for each shade of the chalk):

  • 3/4 cup plaster powder
  • 1/2 cup water
  • 1 teaspoon tempera paint
  • plastic or silicone ice cube trays (ours are from Ikea)


In a bowl mix 1/2 cup water and add 1 teaspoon of tempera paint color of your choice. You can add more or less paint and regulate the color intensity of the chalk. Then mix in 3/4 cup of plaster powder.

In order to make color changing sidewalk chalk you will need several different mixtures that you’ll make separately. The mixture starts to harden very soon, therefore you need to fill the trays very quickly.

Mix different colors together in each mold.

When you’ve filled all the separate molds with different colors, place the trays somewhere dry so the mixture can fully harden. Making chalk this way takes a bit more time (24 – 48 hours).

Once it does you’ll need to gently remove it from the molds. Take care not to break or crumble the chalk.

The best way is to turn the whole tray upside down and place a hand underneath it while pressing gently on top of the tray with the other hand.

This time we made color changing sidewalk chalk in softer shades, but you can make the color very intensive by simply adding more tempera paint to the mixture.

The chalk draws in multiple colors depending on the side of the chalk you use. This way your drawings will always stand out from the crowd. ๐Ÿ˜‰
