The Madrid Open, currently sponsored by Mutua, is a male and female professional tennis tournament, currently held in Madrid, Spain, during the first week of May. The event is classified as an ATP World Tour Masters 1000 event on the Association of Tennis Professionals tour and a Premier Mandatory event on the Women's Tennis Association tour. In the past it has also been known as the Mutua Madrileña Madrid Open and before that the Madrid Masters. Despite having been played on blue courts in the 2012 tournament edition the ATP decided against it for the 2013 edition.
From 1990 through 2008, the tournament was classified as an ATP Masters Series event on the men's tour. The event was held in Essen, Germany in 1995 and Stockholm, Sweden from 1990 through 1994. When the tournament moved from Stockholm to Essen, the Stockholm Open continued as an ATP World Series tournament. From 1996 through 2001, the event was held in Stuttgart, Germany and from 2002 through 2008 at the Madrid Arena. The tournament was played from 1990 through 2008 on indoor hardcourts. In 2009, the surface became clay courts, the venue was changed to the Park Manzanares, and the tournament was expanded to include WTA professionals.
Blue clay 
Businessman and former player Ion Ţiriac, the Romanian owner of the Madrid Masters that since 2009 has been a clay court tournament, proposed a new color of blue clay for all the courts, on the grounds that it would supposedly be better visually, especially for viewers on television. Critics suggested that the adaptation of blue color is a nod to the titular sponsor of the tournament, the Spanish insurance giant Mutua Madrileña. This controversial change was subsequently granted and began to be used in the 2012 edition of the tournament. In 2009 one of the outer tennis courts had already been made of the new surface for the players to test it. Manuel Santana, the Open's current director, has assured that aside from the colour, the surface keeps the same properties as the traditional red clay.
On 1 December 2011, Ţiriac confirmed that the blue clay surface was officially approved for the 2012 edition of the tournament, in both the ATP and WTA circuits.
However due to many top players' concerns over slipping over and not feeling steady on the surface, the Madrid Open returned to the traditional red clay for 2013. Many including Rafael Nadal threatened to boycott the event if this change did not happen.
