Colour Schemes

In order for the app to be accessible to as many people as possible, the colours used should be tested for colour blindness. This ensures that any element does not become hard to spot and text does not become illegible, even if the user is colour blind.

The general colour scheme was tested before creation:

Colour blindness checks for the planned colour scheme

Of particular interest were the colours of the fish. These need to be distinct to any user for certain elements of the gameplay to make sense. This meant some adjustment of the original planned colours for four varieties of small fish:

Initial colours - problems on red-green blindness types
 As can be seen, some of the colours are almost impossible to distinguish if a person is red-green colour blind.

New colours - fish are much easier to tell apart
The adjusted colours are now distinct for those with colour blindness. The simulation tool used can be found here: http://www.etre.com/tools/colourblindsimulator/
