Eating a rainbow of colours ensures kids get a wide range of vitamins and minerals. Learn how to build a colourful, nutritious lunchbox that kids love to open.

Why Colour Matters in Food

Different colours in fruits and vegetables indicate different phytonutrients — plant compounds that support health in various ways.

Colour	Key nutrients	Examples
Red	Lycopene, Vitamin C	Tomatoes, strawberries, capsicum
Orange	Beta-carotene, Vitamin A	Carrots, mandarin, pumpkin
Yellow	Lutein, Vitamin C	Banana, corn, yellow capsicum
Green	Folate, iron, Vitamin K	Cucumber, spinach, peas, kiwi
Blue/Purple	Anthocyanins, antioxidants	Blueberries, grapes, beetroot
White	Allicin, potassium	Apple, pear, cauliflower

Building a Rainbow Lunchbox

Aim for 3–4 colours as a realistic daily goal, and the full rainbow across the week.

Sample Rainbow Lunchbox

🔴 Red: Cherry tomatoes

🟠 Orange: Mandarin segments

🟡 Yellow: Corn on the cob (cut)

🟢 Green: Cucumber slices + snap peas

🟣 Purple: A small handful of grapes

Paired with a wholegrain sandwich or sushi rolls, this makes a nutritionally complete lunch.

Kid-Friendly Rainbow Foods by Season

Summer (Dec–Feb): Strawberries, mango, watermelon, blueberries, cucumber, tomato

Autumn (Mar–May): Grapes, apple, pear, beetroot, carrot, capsicum

Winter (Jun–Aug): Orange, mandarin, kiwi fruit, broccoli, spinach

Spring (Sep–Nov): Strawberries, peas, asparagus, cherries, radishes

Making It Fun

Let kids choose one colour each day to be responsible for.

Use a sectioned bento box so each colour gets its own compartment.

Make a weekly colour chart and tick off colours as they're eaten.

"Rainbow challenge": see how many different colours they can eat in one week.
