TiddlyWiki themes and/or palettes for the visually impaired

[Locke Raven]

My first post ever to a Google Group so here goes. As the topic implies I am looking for a palette or theme that has a limited amount of colour usage. The pale blue on a  blue backgrounds is unreadable. I'm hoping to find a solution where there is a black background where everything else is either green or yellow or w white background with everything else is black. When I say everything I'm meaning the print as well as the boxes, borders and buttons as well.

*Boxes, Borders and Buttons oh my*

Eh, sorry, kinda strayed off there a bit. I want to thank you, Jeremy, for the most amazing work you've accomplished in TW. You've changed the lives of many people by allowing them to record information and associate their thoughts into Tiddlywiki form.

with respect

Hi Locke

Thanks for the post. I'm determined that TiddlyWiki should perform well for all users, irrespective of any impairments. Simon Eigeldinger, a user of assistive reading technology with TiddlyWiki, has given us detailed feedback that has helped us improve usability with screen readers. I'd very much like to similarly address the needs of users with visual impairments.

A few years ago, we had the opportunity at Osmosoft to adapt TiddlyWiki Classic for the needs of a visually impaired user. The users preferred arrangement was to have a high contrast palette with text enlarged so that the laptop screen showed three lines of eight characters, which could be panned up and down the page.

I've created a ticket over at GitHub to talk about implementing the necessary changes:

Are there any other areas to which might need to pay attention?

Best wishes

Jeremy

I have cataracts described by my eye surgeon as "leather-like". The best solution for me has been the Firefox extension called "Blank Your Monitor" which not only fixes the color/contrast problems but it also normalizes the web's page design.

After surgery on the one eye, I can once again see black text on white backgrounds, even light blue text on blue background but I keep BYM on. While good design is a wonderful thing, Content is King.

Hi Matthew

That's very helpful. As a first step, I've improved the core "Contrast" theme so that it is more purely black and white:

​

And here's the 5.1.8 version for comparison:

​

​

I've retained a bright blue as the default link colour. What are your thoughts? Presumably white would be easiest to read, but I'm guessing it would be a shame to lose the ability to distinguish links visually.

The changes are committed here:

https://github.com/Jermolene/TiddlyWiki5/commit/1b25d4b51ac439b1dc3b59dc287a7f5ddf5e61c9

There's a new prerelease with the "Contrast" theme enabled by default:

http://tiddlywiki.com/prerelease

The next step might be to create a new theme for any changes needed to font sizes, margins, etc.

Best wishes

Jeremy.

I see Jeremy is already on top of this. Seems to me a similar discussion happened sometime ago, it might have been on TW Classic. Anyway was working on something else and cobbled together an example of what is available with the palette customization right now. Was thinking of the old amber CRT monitors. Don't know how well it would work or where it might have "broken" the interface.

Good Luck
