Methods and apparatus for controlling illumination

A method, comprising acts of:

• a) providing at least one light source capable of generating variable color radiation without using a color filter;
• and
• b) controlling at least a color of the variable color radiation based on at least one interruption of power supplied to the at least one light source,
• wherein the act b) comprises acts of:
• executing at least one illumination program to control the variable color radiation generated by the at least one light source;
• and
• modifying at least one variable parameter of the at least one illumination program based on the at least one interruption in the power.

A method, comprising acts of:

• a) providing at least one light source capable of generating variable color radiation without using a color filter;
• and
• b) controlling at least a color of the variable color radiation based on at least one interruption of power supplied to the at least one light source,
• wherein the act b) comprises an act of:
• b1) controlling the variable color radiation based on at least one interruption in the power having an interruption duration that is less than or equal to a predetermined duration.

An apparatus, comprising:

• one of a pool and a spa to contain a liquid;
• and
• at least one light source supported by the one of the pool and the spa to illuminate the liquid, the at least one light source being adapted to generate variable color radiation without requiring the use of a color filter;
• and
• at least one controller, coupled to the at least one light source, to control at least a color of the variable color radiation generated by the at least one light source based on at least one interruption of power supplied to the apparatus.

A method, comprising acts of:

• a) providing at least one light source capable of generating variable color radiation without using a color filter;
• and
• b) controlling at least a color of the variable color radiation based on at least one interruption of sower supplied to the at least one light source,
• wherein the act b) comprises an act of:
• b4) selecting and executing at least one illumination program, based on the at least one interruption in the power, so as to control the variable color radiation generated by the at least one light source.
