Forgive me if this sounds pedantic - that's not what I'm going for, just illustrating my thought process!
From a UI-philosophy position, having text enclosed within a block that's visually separated from the background conveys meaning. For example, the background of the block above this text, being slightly darker than this text-block's background, conveys that it's separate. It's obvious to anyone who's visited web forums for years that this means it's a quote from a previous poster.
It conveyed all that meaning without me having to label it with "THIS IS A QUOTE".
To convey that with just borders is possible, but modern web-design standards aren't leaning in that direction. We want Websleuths to grow, and if it looks looks old and outdated, they'll think the content is also old and outdated, and likely leave. That said, our long-time users won't appreciate big change. It's up to me and my team to strike a balance, and that can be harder than writing the code itself!
I could make the background (what is white on the High-Contrast - Light theme) some accent-color. Going with the blue-theme, I could experiment with a light desaturated-blue, and move in a stepped-fashion towards white as we get closer to the actual text-editor.
Thanks for the reply, but I don't think you actually addressed my question. Or maybe you did, I'm not sure. So I will be bit pedantic in this reply, to try to make sure I am clear, and please forgive me if it's too belaboring or feels off-putting, because it's not meant to be. I do appreciate your willingness to work on this and allow feedback and flexibility.
The High Contrast mode [Light} is being offered to accommodate those whose eyes (or personal preferences) are for the easiest readability, right?
And you have all the other other modes that offer fancier color and new "modern" updated feel, for those who would enjoy that.
If I understand you correctly, what I am hearing is that it would be easy to make the background white, but it's not quite as fancy, so it's being made a different color ever so slightly.
Isn't the High Contrast [Light] mode being created and offered to try to get an easy-to-read format for aging eyes, as perhaps its main purpose? So how is opting for the not-quite-white color (which LESSENS the readability in that format) going to be helpful to the subset of your patrons who opt for that format because they want and need the MOST readability possible?
Let me clarify that I am not talking about the quote box background. I understand how that box needs to be a contrasting color scheme to differentiate. When I express the need for a white background, I am talking about the general background on which I write my post and on which it is read. So far, it is being created as some sort of off-white or light blue or light gray or similar background, which only serves to make it less contrast and harder to read for those of us with aging eyes. For me, it makes the black lettering look gray, and harder to read (and more eye strain in using your site), because of the lessened contrast.
My request is that in that one High Contrast [Light} mode, you please do the color modifications in other areas besides the basic place to read and write, rather than sacrificing basic readability. Offering one "maximal readability" option (pure-black letters on pure-white background) in that one color format option still leaves all the other mode options and dark schemes available for those who can easily utilize less contrast and like the variety.
Thanks for your consideration.
