Image Development for my Occupational Therapy Website

Tonal contrast is a significant factor to be aware of when editing the photos for the website. Colours with short wavelengths for example blue are hard for older people to identify.

As we mature into old age our eye’s lens tends to “yellow” and our pupil size shrinks which results in colours looking dimmer and slightly brownish. Also, most of our lives we see colour before form but mature eyes begin to see form before colour (although creatives often continue to see colour first).

To help my identify if my images during editing has a good tonal contrast, I will need to turn the image in to black and white then make adjustments to ensure elderly people find them easy to view.

General guides to colour self help (Taken from


  • In its natural form it is daylight.
  • Helps the mind to be open, clear and receptive.
  • Not good if feeling isolated or cut off.


  • Dark and severe reds tend to have the ability to over-stimulate and agitate.


  • Brighter oranges are very social and gregarious.
  • Deeper oranges like terracottas are very warming.


  • Falls between yellows and oranges.
  • Less irritating to the nervous system than yellow.


  • Bright sharp yellows are very tiring and can trigger migraines and travel sickness.
  • Soft yellows used with bright blues are good for mental stimulation and growth in children.

Bright Greens

  • Those greens often referred to as Kelly Green are found to energise.
  • Used with clear blues and pure white this type of green encourages physical activity.

Dark Greens

  • Works well in areas where you need to concentrate for long periods.
  • Think of the ‘green room’ used by an actor prior to a performance.

Pale Greens

  • Very soothing.

Pale Blues

  • Cooling and helps encourage rest.
  • Balance for over-activity.


  • Useful where fear is stopping activity.


  • Mix of violet and red.
  • Nurturing, promotes intuition, meditative and insightful.


  • Blending of two neutrals.
  • As a mid tone colour it has been used to denote cool rational thinking.
  • Too much of this colour is demotivating.


  • Earthy blend of orange, ochre yellow and black.
  • Denotes dependability.
  • Can make a space feel secure and stable.

In conclusion, keeping the whites bright may keep the mind open, orange can create a warming effect and bright greens work well with clear blues and whites may encourage physical activity – getting up and getting in contact with the council to support your needs.
