Complex classes like Color often do a lot of different things. To break such a class down, we need to identify a cohesive component within that class. A common approach to find such a component is to look for fields/methods that share the same prefixes, or suffixes. You can also have a look at the cohesion graph to spot any un-connected, or weakly-connected components.
Once you have determined the fields that belong together, you can apply the Extract Class refactoring. If the component makes sense as a sub-class, Extract Subclass is also a candidate, and is often faster.
While breaking up the class, it is a good idea to analyze how other classes use Color, and based on these observations, apply Extract Interface, too.

Since your code implements the magic getter
_get, this function will be called for any read access on an undefined variable. You can add the@propertyannotation to your class or interface to document the existence of this variable.If the property has read access only, you can use the @property-read annotation instead.
Of course, you may also just have mistyped another name, in which case you should fix the error.
See also the PhpDoc documentation for @property.
