I'm using the black ANSI color theme in Claude Code v1.0.60.

It works as expected in xterm and urxvt, but in Kitty, the ANSI blue color is not applied.
Please fix this issue, as Kitty is currently unusable because of it.

Command for testing colors used in a screenshot: ! for i in {0..15}; do print -nP "%F{$i}$i %f "; done; echo

urxvt terminal:

kitty terminal:

We've developed a tool called tweakcc which can be used to create custom Claude Code themes and customize existing ones.

@bl-ue thanks, that was my idea too, patch client to remove emoji, change colors :D.
Man, how many billion dollars need to invest to Antropic to just support 16 ANSI colors?
