            Bug ID: 387709
           Summary: Konsole shouldn't turn "\e[1m" into intensive color
                    format.
           Product: konsole
           Version: master
          Platform: Ubuntu Packages
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: font
          Assignee: konsole-devel at kde.org
          Reporter: cat.hook31894 at gmail.com
  Target Milestone: ---

When I was trying the Solarized theme in Konsole, I found that the output of
`ls` command became much less colorful compared to the one run in OSX's buildin
terminal app.  (See also: https://bugs.kde.org/show_bug.cgi?id=364660)

The root cause is that Solarized theme somehow considers those 16 system colors
to be not related colors, but Konsole considers colors 8~15 as the intensive
style of colors 0~7.  Therefore, when Konsole encounters the escape character
"\e[1m", Konsole will render the rest of the text in intensive color instead of
bold font style.

These logic leads to another problem:
Both "\e[1;34m" and "\e[94m" will lead to same effect of color style.

I think a possible solution is to use "\e[1m" for bold fonts, "\e[9Xm" for
intensive color.  And I also implemented it at here:
https://github.com/cathook/kde-konsole/tree/master
(commit diff URL:
https://github.com/cathook/kde-konsole/commit/7a1573b3cce1d562b1dc053cb89f8abca2fc7642)

Another solution might be to extend the color palette from 30 (3 for
foreground, 3 for background, 8 * 3 for normal/intensive/faint system colors)
into 54 (3 for foreground, 3 for background, 16 * 3 for normal/intensive/faint
system colors).
