What terminal and color scheme are you using?

[nschloe]

gnome-terminal, solarized-dark.

[riobard]

Solarized colors do not exactly match the color scheme of your terminal. See the table at http://ethanschoonover.com/solarized

The Values

L*a*b values are canonical (White D65, Reference D50), other values are matched in sRGB space.

Solarized blue is not #0087ff but rather #268bd2. #0087ff is the closest match if you use the terminal's default color scheme. For best result you should change your terminal's color scheme. Unfortunately Solarized does not offer a prebuilt color scheme for gnome-terminal.

The palette I'm using is gnome-terminal-colors-solarized, and it looks quite accurate:

Indeed, blue is #268bd2 here.

In the bash-powerline script, I see

readonly FG_BLUE="\[$(tput setaf 33)\]"

Doesn't this set blue to #0087ff?

[riobard]

It sets the foreground to color 33, and your terminal decides what actual color to use for color 33. What's the value of $TERM in your terminal?

It sets the foreground to color 33, and your terminal decides what actual color to use for color 33.

Hm, really? This seems to be the issue then, 33 produces #0087ff for me, tested with

for i in {0..255} ; do
     printf "\x1b[48;5;%sm%3d\e[0m " "$i" "$i";
     if (( i == 15 )) || (( i > 15 )) && (( (i-15) % 6 == 0 )); then
         printf "\n";
     fi;
done

$ echo $TERM
xterm-256color

[riobard]

It's indeed very strange. Solarized used color 33 as blue for 256-color terminals, and it should produce sRGB(38, 139, 210) if your terminal is properly configured. Maybe you should try a different terminal emulator and see if this is a bug in gnome-terminal.

Alright, I'll dig more in this direction. Thanks for the help! Will reopen in case I find a bug in bash-powerline.
