You only need a place to start.
You do not have to finish a whole page in one sitting. Pick a design that catches your eye, choose a few colours, and begin with one small area. A wheel, a wing or a shirt can be enough to get you going.
Pencils, pens or markers?
Coloured pencils are an easy starting point. A light first layer leaves room to add more colour later. Try changing the pressure rather than pressing hard from the start, and keep a scrap sheet nearby to test combinations.
If you prefer pens or markers, test a small area first. Different inks behave differently on printed paper. The designs in this collection are single-sided, but ink may still bleed through or transfer to the next sheet.
A useful habit: put a spare sheet of paper or thin card behind the page you are colouring. Let wet ink dry before closing the book. Use materials that are appropriate for the person colouring.
Choose a small palette.
Try starting with three colours: one main colour, a second for contrast and a darker shade for details. Using a small set of colours can help a page feel connected. You can always add another later.
Supercars: build your dream garage.
Try a two-colour paint scheme, add a contrasting detail, or colour the same kind of car in a completely unexpected shade. The finished garage is yours.
Trucks: make a matching fleet.
Give your fleet a matching colour scheme or make every truck different. Try using one bright main colour with a darker shade for contrast.
WW2 Fighter Planes: explore a different palette.
Choose a small palette of greens, greys and browns for a camouflage-inspired look, or use bright colours for an imaginative finish. The book is for colouring; it is not an aircraft identification guide.
Football: bring your own colours.
Start with two colours inspired by your favourite team, then add a third for the background or small details. Or invent a colour scheme for a team of your own.
Make it a shared activity.
Colouring together does not have to mean working in the same way. Each person can choose a page and a palette. Compare the colours you picked, swap a pencil or two, and let everyone work at their own pace.
For children, an adult can help choose suitable materials and a design they will enjoy. There is no need to treat staying inside every line as the main goal.
Find a subject you enjoy.
The best starting point is something you would like to spend time with. Explore the four books, see what is inside each one, and choose the next page for your imagination.
