I did an unsolicited redesign of a wikipedia article page a few months ago (mostly a tweak to the current layout). Although Wikipedia is a website rather than an app, the site's pages are are quite stark and many pages feel bereft of colour. In my (unsolicited) redesign I added colour to soften the appearance of the page and to highlight elements. Are the colours superfluous? Or do they make the page or site more pleasant to read? Opinions very welcome :-)
