This activity transforms a dark room into an art studio where your child paints with light. By taping coloured cellophane or tissue paper over torch ends, toddlers project bold colours onto walls and ceilings — and discover that overlapping colours make new ones. The dark becomes essential, not threatening, because the colours only work when the lights are off. It's a gentle, child-led way to build positive associations with dimness.

Best for this moment

for calmer, lower-pressure moments, especially when you need an indoor option.

Parent tip

Set out flashlight and rubber bands before inviting your toddler in so the first minute feels smooth.

What success looks like

A good outcome is a few minutes of engaged play, some back-and-forth with you, and a small sign of progress in cognitive skills.

Instructions

Get ready
  • Cut squares of tissue paper in red, blue, and yellow — large enough to cover the torch end.
  • Secure one colour over each torch using a rubber band (you'll need at least two torches).
  1. Cut squares of tissue paper in red, blue, and yellow — large enough to cover the torch end.
  2. Secure one colour over each torch using a rubber band (you'll need at least two torches).
  3. Dim the room together and give your child the first colour torch.
  4. Shine it on the wall and say 'Look, we made a red circle! What happens if we move it?'
  5. Introduce the second torch and overlap the two beams — 'Red and blue together make... purple!'
  6. Let your child experiment freely: big circles, small circles, fast movements, slow swirls.
  7. Swap colours around and explore all the combinations — which new colour is their favourite?
  8. Wind down by shining both torches on the ceiling and slowly dimming them with your hands: 'The colours are going to sleep now... goodnight, colours.'

Why it helps

This activity addresses fear of the dark through a cognitive reappraisal framework — helping the child reinterpret the dark as a useful and exciting environment rather than a threatening one. The colour mixing introduces early scientific reasoning (cause and effect, prediction) while the creative freedom builds a sense of agency. When a child chooses to turn the lights off because the activity requires it, they are exercising voluntary approach behaviour toward the feared stimulus, which is the most powerful form of exposure therapy.

Variations

  • Cut shapes out of card and hold them in front of the torch to project shape shadows inside the colour circles.
  • For a collaborative version, one person holds the torch while the other moves a white sheet of paper to 'catch' the colours.
  • Spray a fine mist of water into the beam to see the colour in the air — this works beautifully and creates a gasp-worthy moment.

Safety tips

  • Supervise rubber bands carefully — remove them at the end of the activity and store out of reach.
  • Remind children not to shine torches directly into anyone's eyes, even through the tissue paper.
  • If using a spray bottle, protect the floor from slipping by placing a towel down first.

When to pause and seek extra support

Stop if your child becomes distressed, unsafe, or consistently frustrated by the activity. If play, behaviour, or development worries keep showing up across settings, check in with a qualified professional.
