Usability issue with large images on start page

[tripleee]

A user in chat highlighted (sic) a problem with the accessibility of the metasmoke start page. For them, the large images with a white background are a problem.

Their suggestion is to set the background to "canvas" instead of hardcoding white. I have not yet explored whether that is something we can easily do in Rails.

Tangentially, neither https://www.w3.org/WAI/tutorials/images/ nor https://developer.mozilla.org/en-US/docs/Web/Accessibility/Understanding_Colors_and_Luminance discuss this particular usability issue.

To be fair, W3 accessibility guidelines are pretty bad in general. They seem to think you can test for screenreaders by checking for the presence of aria tag attributes and the absence of keyboard traps, without actually trying it on a screenreader; or even just knock your mouse away and try it with just the keyboard.

We're having this stupid checkbox-accessability fixup problem at work right now; the software still won't work and nobody actually cares the customer just cares we pass the automated test, which is largely orthogonal to making it work.
