Colour-preserving
Colour preservation is a property of glider reflectors and turners. A reflector is said to be colour-preserving (abbreviated as CP) if it does not change the colour of a glider. A reflector that is not colour-preserving is said to be colour-changing (abbreviated as CC).
As above, colour preservation is only defined for glider-to-glider conduits, and is not well-defined for general conduits with an arbitrary input and arbitrary output.[1]
It is, however, possible to determine whether the colour preservation property of a circuit is affected, when some conduit is replaced by another conduit with the same input type and the same output type.[2] For example, replacing an Fx77 instance with an Fx153 conduit toggles the colour of any subsequent output gliders.[3]
