Accessibility awareness: Colour contrast

To mark National Inclusion Week (15th to 21st September) this month’s accessibility campaign focuses on the often overlooked aspect of: Colour contrast.

Whether you’re creating a Word document, PowerPoint presentation, or publishing content online, colour contrast affects how easily people can read and understand your content.

Poor contrast can make information inaccessible to:

  • People with Colour Vision Deficiency (CVD)
  • Users of assistive technology
  • Older adults and those with reduced vision
  • Anyone using screens in bright environments

Cllr Nosheen Dad, Cabinet Member for Adult Social Care and Corporate said:

“Accessibility is about making sure everyone can take part, and that starts with how we present information. Colour contrast might seem like a small detail, but it can make a big difference — especially for people with visual impairments or those using assistive technology. I’m proud that Kirklees is raising awareness and helping our services, partners and communities become more inclusive in everything they do.”
