Foam and spray, or a switch that trips: either way, a calm surface broken.
Breaker is a light grey, close to white.
It can be described as light, pale and neutral.
Set in black, because black reads best on it.
In fluid dynamics and nautical terminology, a break or breaker is a wave with enough energy to "break" at its peak, reaching a critical level at which linear energy transforms into wave turbulence energy with a distinct forward curve. At this point, simple physical models that describe wave dynamics often become invalid, particularly those that assume linear behaviour.
Read on WikipediaA circuit breaker is an electrical safety device designed to protect an electrical circuit from damage caused by current in excess of that which the equipment can safely carry (overcurrent). Its basic function is to interrupt current flow to protect equipment and to prevent fire. Unlike a fuse, which interrupts once and then must be replaced, a circuit breaker can be reset to resume normal operation.
