Colour mixing is one of the first art activities that most Montessori Primary children engage in, and it is a fundamental concept that children can later build on in other activities, including Reggio-style provocations.

Today, I wanted to share with you five successful invitations that my children enjoyed, a new favourite book, and some fun (mess-free) colour mixing ideas from my fellow bloggers.

10 Colour Mixing Activites and Mix It Up Book Review -- some of the color mixing ideas are mess-free and some could be considered science experiments

Mix it Up by Herve Tullet was a book I was initially a bit skeptical about — I mean, why read about colour mixing when you could actually just mix colours?! But actually reading the book with my preschoolers brought out the magic of the book.

Mix It Up is an interactive book, like Don’t Push the Button, Press Here, or similar titles, encouraging kids to pretend to blend colours, tilt and shake the book to make colours run, and smoosh the pages together to make inkblot-style paintings, all while learning about colour mixing, shades, and hues. It’s a great choice for the mess-averse or sensory-sensitive child, who might want to “practice” with the book for awhile before being introduced to actual colour mixing; but it was also a huge hit with my mess-happy children who loved the interaction and transformation elements of the book.

I was actually surprised at how often Ella picked up this book, considering she has an art room that she can freely paint in whenever she wants. I think it is a combination of the positive, affirmative language (“You’ve got the magic touch!”) and the approachable yet precise results. Most of the book is globs and dots of paint, so children can actually create what they are seeing — and genuinely feel like the results they are “causing” from page to page are paintings that they could actually create.

Mix It Up is definitely a launch pad into real-life art exploration, so here are 10 Colour-Mixing Activities to try after you’ve read the book (or whenever!):

black and white painting (6)One of the most important Reggio provocations (to me) is setting out black and white paints, and allowing children to discover how they mix and interact.

Our color mixing lab is definitely a favorite way to experiment with mixing colors.

(You can also buy a complete kit to do this the proper Montessori way.)

I love this milk and dish soap experiment we did forever ago, and I can’t believe I haven’t shared it here before yesterday! Colour mixing and science, what’s not to love?

The following ideas are mess-free colour mixing activities from my fellow Kid Blogger Network bloggers:


This fizzing colour mixing activity by Blog Me Mom is both an art invitation, and a science experiment! I love these pipettes from Montessori Services (50 for $3) for activities like this.

And, probably my favourite mess-free colour-mixing activity idea:
