Colour Blindness

samplesIf you are colour blind it can be hard to distinguish between different colours. Free software is available to help you to:

  • identify a colour within something on your computer
  • mobile apps can also help you identify colours in your environment by using the camera on your phone or tablet device
  • help discriminate between colours by making colours darker or lighter, or increasing saturation or by using hatching

Mac, Windows, iPhone and iPad
