If you are anything like me, you’ll know that keeping children entertained – especially on rainy days or during school holidays – often requires a little creativity.
Over the years we’ve tried everything from simple crafts to baking afternoons and printable activities. One thing that always works in our house is colouring. It’s simple, calming and works for a wide range of ages.

Recently we discovered a website that adds a fun twist to traditional colouring pages – Colomio – and it’s quickly become one of our favourite easy activities.
Let Kids Create Their Own Colouring Pages with AI
One of the most exciting features on Colomio is the AI colouring page generator.
Instead of searching through endless printable sheets trying to find something your child likes, they can simply type their idea and the site creates a custom colouring page for them.
For example, you might try prompts like:
- a dragon flying over a castle
- a cute puppy in a superhero costume
- a dinosaur riding a skateboard
- a princess with a friendly dragon
Within seconds, the AI turns the idea into a clean black-and-white colouring sheet that you can print at home.
Children absolutely love seeing their own ideas turned into pictures, and it’s a great way to encourage imagination and storytelling too. My boys spent far longer than usual colouring because they had helped create the picture themselves.
And the best part? You can create these colouring pages completely free, which makes it perfect for classrooms, rainy afternoons or school holiday activities.

Colour the Pictures Online Too
Another feature that really stands out is that the colouring pages don’t have to be printed if you don’t want them to be.
Colomio also lets kids colour the pictures directly online using a digital colouring tool. This is particularly handy if you’re travelling or if you want a quick activity without getting out pencils and felt-tips.
Even better, once the artwork is finished it can be shared or published online. For children who are proud of their creations, this adds a lovely sense of achievement and encourages them to keep creating.
A Huge Library of Colouring Pages
If you don’t want to create your own images, Colomio also offers a large collection of ready-made colouring pages.
There are designs for all sorts of interests, including:
- animals
- vehicles
- fantasy characters
- seasonal themes
- patterns and mandalas
This makes it easy to find something suitable, whether you’re planning a quiet afternoon activity, a classroom printable, or something to keep kids entertained during travel.
Why Colouring Is Still One of the Best Activities for Kids
Colouring might seem simple, but it offers lots of benefits for children. It helps develop:
- fine motor skills
- focus and patience
- creativity and self-expression
It’s also one of those rare activities that works for a wide age range. Younger children can enjoy filling in simple pictures, while older kids can spend more time experimenting with colours and details.

A Great Idea for Rainy Days or Quiet Time
If you’re looking for a simple way to keep kids busy without lots of preparation, Colomio is definitely worth exploring.
The combination of AI-generated colouring pages, the ability to colour online, and the option to share finished artwork makes it feel fresh and interactive compared to traditional printables.
And anything that encourages creativity while giving parents five minutes to drink a cup of tea while it’s still hot is always a win in my book.
