Accessibility - Visual Impairment Function

[ghost]

A wireframe design and justification that showcases the option to alter the contrast, to include a series of varied contrasts. For those with strong visual impairments a black background option with yellow text will be part of this.

Original user testing feedback

From https://github.com/alan-turing-institute/AutisticaCitizenScience/blob/master/community-recommendations/user-tests/sprint-6-feedback/summary-sprint6-feedback.md

• P i: Suggestion: Possibility to change the colour scheme
• A D d: “I would appreciate pastel colors, because the screen is so bright. It is probably alright, it might be just the colouring. It might be good to have a colour bar to adapt the background.”
• A D d: “As it is at the moment I would probably not use it, because I find the colours too intense.”
• A D d: Theme does not need to be a dark theme, but “just not so bright. I think more about pastel colours. I find it hard to read on. I had a test once and they gave me a kind of ‘pinky’ background, which I found easier to read on.”
• A C d: “[The contrast] is a little bit too heavy for me, but then I am short sighted, I am wearing my reading glasses. I don’t know if other people who got strong visual impairments would need that kind of contrast. I am just learning about this, that people with strong visual impairments do better with black background and yellow. So I don’t know if at any point of this ‘load up an experience’ you could have an alternative one, saying ‘do you have a visual impairment? Would you like to use this template?”

Very useful work! @jiraslama I appreciate that you have included designs to meet accesibility needs as well as giving options to suit individual preferences. Both are important, and it's great that we are able to meet this requirement from the community. Ready to test as part of the prototype I reckon.

Made issue #369 to create an accessibility checklist that can be used for the MVP and going forward. Closing this along with other accessibility checklist items for now.
