I used to set bold for intensive color. But after upgrading to kde 3.5.4, they are gone. How to reproduce: Settings -> Configure Konsole... -> Schema -> pick some colors and check "Bold" -> Apply
It's a known breakage in latest konsole by upstream.
Has a KDE bug been filed for this? I cannot find it at bugs.kde.org. This was my problem report: http://article.gmane.org/gmane.linux.gentoo.user/168575
Created attachment 96314 [details, diff] undoes the colour-related changes in 3.5.4 to bring bold back to the Konsole
Fixed in -r1
