Klein Blue scores Lc -12 as text — here's the two-slot fix

Short summary

A Klein Blue terminal theme for Claude Code solved an accessibility problem: the pure pigment (002FA7) had unreadable contrast (Lc -12) for body text. The solution split decorative and readable layers—pure IKB for borders and highlights, A8BEF0 for permission prompts and readable text—maintaining the aesthetic while passing APCA contrast standards (body ≥90, subtle ≥75, muted ≥45, accents ≥60). Requires dark-ansi theme and offers four design variations.

• •Two-slot color approach: pure IKB for decorative elements, A8BEF0 for readable text with APCA compliance
• •Solves Lc -12 contrast problem while preserving Klein Blue aesthetic across long terminal sessions
• •Requires dark-ansi theme setting; four theme variations ship with deliberate accessibility/aesthetic tradeoffs
