I presume this subsite was aiming for a light pastel-y look, but I think it's taken it way too far. Have a look at these two screenshots of questions on different SE sites:
The problem (or not, depending on where you're sitting)
Notice the difference in the visibility of the background colours of two types of highlight (annotated with their R,G,B values for Unix/Linux), familiar across StackExchange:
- the light blue that indicates the question-asker when their name appears in their question or in comments on answers
- the grey that highlights block or inline excerpts of
At least on the screens I've tried, which are modern panels set to 50% for all parameters, these colours are so light that they're almost imperceptible - and therefore functionally almost useless. In particular, I had to squint for about 20 seconds at my monitor, and stoop down to get a slightly better angle, just to work out whether or not the person commenting on the top answer was the OP.
'OP or not' is a status that is extremely relevant when reading discussions and was presumably the rationale behind this highlight colour (on better themes). As for the
code background, this is, I suppose, less critical due to the fact that the padding and font provide other visual signifiers - but it's still very inconsistent with the other SE sites that have practically visible backgrounds.
So, what's the point of highlighting any of this, if it's not visible without eye and/or neck strain? I'm pretty sure I'd be considered a very able user in terms of accessibility, and this theme just doesn't work for me, so I can only wonder what it must be like for those with additional requirements reading this.
Please could you revise the theme to have a usable degree of contrast, to grant some utility to these backgrounds, same as they provide in other SE sites?
