LONDON — Red. Blue. Gold.

No white for Misty May-Treanor’s Olympic manicure. What would be the point of that?

Gold is far more fitting for the two-time Olympic beach volleyball champion, anyway.

May-Treanor, who paints her own nails despite a shaky right hand that is only a slight annoyance, plans to tidy up her look now that she and partner Kerri Walsh Jennings are done with pool play and on to the single-elimination rounds, beginning tonight.

While those two Americans take their next step, Michael Phelps is set to swim his final individual race of the London Games today in the 100-meter butterfly.

On Thursday night, Phelps won the 200 individual medley for his first individual gold of the games. It was his 16th gold and 20th career Olympic medal, extending his records in both categories. He’s looking to defend his memorable butterfly gold from Beijing, where he edged Serbia’s Milorad Cavic by only one-hundredth of a second.

May-Treanor revealed the other day that she has a tremor in her right hand. And, no, she insists, it’s nothing to be concerned about — she hasn’t even discussed it with her doctor. But when she tried to help a friend with her makeup in London, she quickly decided that it was a bad move.

“I have a shaking right hand; I have a tremor,” May-Treanor said, picking at her fingers. “It’s hard to paint my nails nicely. I was going to paint them red, white and blue, but I didn’t know what to do with the white. So I went with gold.”

Do forgive the American star if the manicure isn’t quite as spot on as her serve. Every little touch — literally, too — means so much right now as her brilliant career winds down.

This is May-Treanor’s last Olympics. She already celebrated her 35th birthday this week at central London’s picturesque Horse Guards Parade with a trio of pastries, each topped with — what else? — a gold candle.

“Oooh, gold candles, I like that,” May-Treanor said.

Three gold medals would be even sweeter for this pair of American megastars.

Are those sparkly nails in some way a message to everybody else in the Olympic tournament to move out of the way?

“Because she has the gold, probably,” Italy’s Greta Cicolari said Thursday after she and partner Marta Menegatti advanced No. 1 out of their pool at 3-0.

Yet the U.S. team showed a brief, rare moment of vulnerability Wednesday night by dropping a set to Austrian sisters Doris and Stefanie Schwaiger. May-Treanor and Walsh Jennings rallied back for a 17-21, 21-8, 15-10 victory.

Spanning three Olympics, the Americans had gone 16 straight matches and 32 consecutive sets without dropping one.
