US Open 2026 Monday 31 August: the New York-blue tennis nail trend

1. US Open 2026 — calendar and colour code

US Open 2026 runs from Monday 31 August to Sunday 13 September at Flushing Meadows, New York. Last Grand Slam of season.

Signature US Open chromatic code:

• Vivid cobalt blue — hard-court surface colour.
• White — ball, court lines, classic kits.
• Neon yellow — iconic ball colour.
• Silver / chrome — signage, sponsors design.

Vs. Wimbledon (lawn green + strict white, see our Wimbledon guide): more saturated palette, more pop, more American.
