A new theme has been proposed many times for this forum, and so far not taken up. Let’s break the impasse!
I made the current default theme based on the now-legacy SuttaCentral. We tried updating to match the new site, but the theme was broken in too many ways. We also have a bunch of rather hastily cobbled-together themes. These are neither pretty nor accessible. Nor are they up-to-date with Discourse.
get rid of all old themes
use properly designed new themes
offer a few carefully selected themes made by designers, including light and dark
Both default theme and all optional themes must satisfy these.
SuttaCentral’s Skolar fonts. Theme fonts must be replaced.
SC lotus logo
default theme must be highly accessible.
making me happy
Using SC color scheme.
making everyone else happy
Discourse Light (plain but clear, well-tested, highly accessible)
Grey Amber: dark with bright yellow accents, I use this myself
Solarized (this uses the dark solarized color scheme, a highly tested and rigorous set of colors that’s widely used by programmers).
Sunflower. It’s bright, cheery, simple, highly accessible, and its yellow colors are not too different from SC. This would be my second choice for a default.
I actually prefer if the look and feel of the Discourse side of things is very distinct from the main site. Especially the favicon (I’d say the favicon being different from the main site is an absolute must.)
I see many people online thinking that the discussion forum is the same thing as the sutta site. Maybe a different look and feel wouldn’t fix that, but it couldn’t hurt.
Sunflower: my eye automatically sees the separation of elements ( I.e posts, titles, menu bar etc) and thus makes it easier ( for me anyway) to scan and browse. Maybe because I am used to this layout/ colouring scheme, I may be subconsciously biased. Asked my partner who doesn’t use the forum to give their opinion, went for sunflower straightaway.
Zero noise: beautiful to look at but does not do the above for me. Also looks like a minimal blogging theme
