Does text colour matter? Specifically, online, is black print on a white page easier to read than white print on a black page? Yes it is because it’s easier on your eyes. We’re also accustomed to this colour scheme based on all the newspapers and books we’ve read.
I’ve always believed black-on-white is better and a quick search found general agreement. Apparently the white-on-black colour scheme, or inverted text, decreases readership by 50%.
So if you think your website or blog should have a black or dark background because it will be cool and stand out; think again. And if your site currently uses an inverted text colour scheme, ask your community what they think.
