Get Enum Instance from Class<? extends Enum> using String value?

I'm finding it difficult to put the exact question into words, so I'll just give an example.

I have two Enum types:

enum Shape {
    CAT, DOG;
}

enum Color {
    BLUE, RED;
}

I have a method:

public Object getInstance(String value, Class<?> type);

I would like to use the method like:

// someValue is probably "RED", and someEnumClass is probably Color.class
Color c = getInstance(someValue, someEnumClass);

I've been having trouble determining exactly how to implement getInstance(). Once you know the exact Enum class that you want to instantiate, it's easy:

Color.valueOf("RED");

But how can this above line be accomplished with an unknown Class? (It is, however, known that the someEnumClass is a subclass of Enum.)

Thanks!
