I decided it was time to start looking at what colour palettes could potentially be suitable for my wayfinding system. I came across this particular image on Pinterest and it stood out to me as something I could perhaps use.
I was really attracted to the bright, almost luminous colours and felt it could potentially be useful within the wayfinding system.
After research into the yellowing of the eye lens as we age, I decided to run a few tests within Illustrator to see how the colours would appear under a yellow hue. I did feel that the luminous colours weren't quite as effective, whereas when I placed a standard set of primary colours under the hue, they were still really quite distinguishable.
Following on from this, I went onto Adobe Kuler and created 6 palettes of vibrant, bright colours with links to the primary palette.
Again, I place the yellow hue over the colours to see how they would appear through an elderly person's eyes with deterioration.
The bottom left palette with the more muted tones became really quite flat and demonstrated that these types of shades would be unsuitable to use.
The brighter tones, however, such as the top 4 palettes were a lot clearer and easier to distinguish.
Using the yellow hues demonstrates an extreme of this factor - not all patients will be affected by this yellowing of the lens, and the people who do experience it will do so in different degrees. Some only slightly, some quite prominently. Looking at how the colours appear under a yellow hue is something that should definitely be taken into consideration, but not something that should be the sole reason and purpose for picking a certain colour palette.
