Mastodon has a high-contrast option, but for many people, it's not enough.

At https://mementomori.social, we have two extra themes for people who need more: Ultra accessible and Ultra accessible Plus. They're designed for people with visual impairments, colour blindness or tunnel vision.

For example, people with retinitis pigmentosa often use 200-300% zoom and need bigger elements. They need large, high-contrast text and elements throughout the interface. Everything has to be easy to find and see, and content needs to stay in the same place. So we have a theme with:

- A black background and white text
- Extra-large text without excessive browser zoom, so elements work properly
- Links, mentions and hashtags each in their own colour
- Clear outlines on buttons and fields
- And more

These improvements don't just help people with low vision. They also help people with motoric impairments who need everything to work with as few clicks and as little movement as possible. We've also improved the layout in our fork: the composer form stays in the same place at the top, and notifications are at the top too. This means people don't need to scroll or search for them, whether they're using their eyes or assistive devices such as a mouse, touchscreens, touchpads or braille keyboards.

You can switch themes in Preferences → Appearance → Site theme.

Just FYI, in case you're disabled and need more than Mastodon offers by default. I try to make the accessibility features in our Mastodon web version as good as I can. I have a dedicated tester (my wife) at home who has these impairments, so we can test with real-world examples.
