The Listening Room Turns Lemon

[Color guide — coloring.today / the-listening-room-turns-lemon]
Apply this palette to the design requested above. Preserve the requested layout, content, and interactions. If an explicit requirement conflicts with this color guide, identify the conflict instead of silently overriding it.

Text: Black Needle #17151B
Primary: Royal Slot #6233B8
Highlight: Turquoise Select #006B67
Accent: Detail Gray #666A6A
Background: Lemon Program #F5F0A8

Mood: A fresh daylight music program in pale lemon, near-black, royal purple, dark turquoise, and charcoal gray
Suggested uses: Music events
Application note: Use Lemon Program with Black Needle for the main schedule and notes. Place artist slots on Royal Slot, the labeled selected stage or session on Turquoise Select, and supporting details on Detail Gray, all with lemon text and separate placement on the pale canvas.
Avoid: Do not use Black Needle text on Royal Slot, Turquoise Select, or Detail Gray; the ratios are about 2.32:1, 2.85:1, and 3.31:1. Use Lemon Program text at about 6.67:1, 5.43:1, and 4.67:1. Keep purple, turquoise, and gray blocks separated by lemon space.
Use approximately 55% background, 30% primary, and 15% highlight across large surfaces. These ratios are a starting point, not a rigid rule. Use text and accent colors according to their roles.

Keep the original HEX values. Choose readable text/background pairings without silently changing the palette. Do not introduce unrelated colors.

Text/background contrast: 15.45:1. This is one measured pair, not a guarantee for the whole palette. Check every actual text/background pairing against WCAG AA. Prefer readable combinations from the original colors, keep visible keyboard focus, and never communicate state through color alone. If no original pairing meets the requirement, propose a separately labeled derived color with its original HEX, proposed HEX, purpose and measured contrast. Never overwrite the source palette.
