Note: There is a newer version of this specification see VEC 2.1.0

Specifies a color value. A color is always defined by a key value. What color is meant by this key value is defined by a standard reference system (e.g. RAL).

For example, if a RAL color should be expressed in the terms of the VEC the referenceSystem would be "RAL", the key would be the RAL number defined by the standard (e.g. "1003" for signal yellow).

Attributes of the type Color normally have the multiplicity [0..*]. This means that such an attribute can have a value for different referenceSystems (e.g. RAL, RGB,...). It must not have multiple values for the same ReferenceSystem.
