Terminal themes optimize for code. Claude Code isn't code.

Short summary

Claude Code outputs mostly prose rather than code, requiring terminal themes optimized for reading paragraph-length text at body size. The author created klein-blue themes using APCA contrast metrics (Lc ≥90 for body text) and split Yves Klein's IKB pigment across separate ANSI slots to solve the visibility constraint. Open-source installation available for Terminal.app on macOS.

• •Terminal themes optimize for code syntax, but Claude Code is 80% English prose requiring comfortable sustained reading
• •APCA contrast verification ensures accessible body text (Lc ≥90) while decorative IKB goes to UI chrome only
• •Open-source Klein Blue themes with git clone installation and rollback via restore.sh
