The original multi-colored, no-line tennis court has eleven separate colored areas with no segregating lines.
Specifically, the court lacks a line dividing the service courts that is two inches wide and twenty-one feet long, and within the rules of tennis, this line is considered to be a part of both service zones.
During play, a tennis ball served that hits the shared line is playable from either side service positions.
In the absence of the line the size of both service areas deviates from the rules because each court is one inch (2.5 centimeters) narrower than specified by the USTA and the ITF.
The multi-colored court used by the Advanta WTT sponsored league in 2008–09 is a compromise in that it has both white lines and the colored areas that satisfies both the rules of the tennis organizations and media appeal.
