Bernie Jenny from Monash University in Australia has developed Color Oracle as a free colour deficiency simulator for Windows, Mac and Linux. When designing any software, apps or websites it allows you to check the colour choices.
This download works on older operating systems as well as the latest ones using Java, but it is important to follow the developer’s instructions for each operating system. It is very easy to use on a Windows machine where the app sits in the system tray and can be used at any time when testing colour options by selecting an area on the screen.
Another trick when designing web pages or other documents is to view them in grey scale or print them out to test readability.
This strategy comes thanks to Andy Eachus at University of Huddersfield.
If you want to learn about digital accessibility in a fun way try the Accessibility Maze Game developed by The Chang School, Ryerson University in Ontario, Canada. It takes a bit of working out and you may not get to all the levels but have a go!
Helen Wilson has very kindly shared her link to SCULPT for Accessibility. Usually we receive strategies that relate to student’s work, but in this case, this is a set of resources that aim “to build awareness for the six basics to remember when creating accessible documents aimed at the wider workforce in a local authority or teachers creating learning resources.”
The Visolve webpage or download allows you to check to see if colours are sufficiently distinguishable from each other. This can help those with colour vision deficiency or colour blindness. You can upload an image and it will provide you with the original view and other selected options such as Red-Green transform, Blue-Yellow transform, Saturation increase, Red, Yellow, Green or Blue filter and with added hatching.
Visolve is also available as an app for iPhones or on Windows and Mac.desktop computers.
Here are some useful, free applications I came across for a needs assessment I have just completed.
Colorblind Assistant – PC – Hover mouse over pixel in any running application – Excel/Powerpoint/PDF/Word etc, and the program displays the colours name.
“Colorblind Assistant is free software that instantly picks the color from the mouse pointer, providing you with a written name of the color, as well as other useful data such as RGB values and bar graphs, brightness and saturation.” It is available as an Android app on Google Play.
Color ID Free – iPhone and Android – Point phone or tablet device at any object and software displays name of currently viewed colour.
“Color Identifier uses the camera on your iPhone or iPod touch to speak the names of colors in real-time. It’s an Augmented Reality app for discovering the names of the colors around you!”
My student was a Pharmacology student who was having difficulty with graphs, lab equipment, dissection. Tested the phone app with various items I had around, and it was very good. As it is on a portable device, it is ideal for lab/field work.

According to Stuart Ball this free Seeing AI iPhone or iPad app has multiple benefits for those with visual impairments or who are blind. It has been developed by Microsoft so has the ‘swiss army knife approach’ according to AccessWorld to telling you about the world around you. It searches out light sources, identifies colours and money and describes them using text to speech. It will recognise a person is approaching and offer a description. Barcodes can be read and optical character recognition is used for documents etc. Clear handwriting can be deciphered and scenes described.
