Wellspa pools have different coloured underwater lighting. By using the controller, you can choose the colour you desire.
Chromotherapy or colour therapy works by electromagnetic waves of different wavelengths penetrating the tissues and carrying with them a certain type of energy. Each colour emits different energy and therefore the colours affect the human body in different ways.
Colourful lighting also gives the pool a fresh look, as the pool outer edge/perimeter is also connected to the underwater lights.
