Recolouring digital images

I can explain the impact of changing the colours in a digital image.

These resources will be removed by end of Summer Term 2025.

Switch to our new teaching resources now - designed by teachers and leading subject experts, and tested in classrooms.

These resources were created for remote use during the pandemic and are not designed for classroom teaching.

Lesson details

Key learning points

  1. Digital images can be recoloured.
  2. The colouring of an image can evoke different feelings and thoughts.
  3. Computers make it easy to experiment with different colour effects.

Keywords

  • Effects - changes that are applied to give a different result

  • Colouring - changing the colour of something

Common misconception

Changing image colouring will make everyone think and feel the same way about the image.

Lots of people might have similar feelings but not everyone will necessarily have the same thoughts and feelings.
