Why does Colors.cs use a Dictionary for storing the colors?

I'm talking about the Colors.cs file found at modules/mono/glue/GodotSharp/GodotSharp/Core/Colors.cs.

This file has a Dictionary<string, Color> which stores a list of colors. Accessing any of these colors is then done like so:
public static Color AliceBlue { get { return namedColors["ALICEBLUE"]; } }

Why is the implementation not just done like the following?
public static readonly Color AliceBlue = new Color(0.94f, 0.97f, 1.00f);

What's the need for the dictionary when we have a getter for every dictionary entry anyway?

I don't know much about C# in Godot, but the Color() constructor can also accept a String that matches one of those colours, and returns it as a result.

Ah yeah, you're right (kind of). There is no constructor in the C# code but there is a function in the Color struct like so:
public static Color ColorN(string name, float alpha = 1f)

That's a weird name for the function but this nevertheless justifies the use of a dictionary. Though I'm not sure why this isn't just another ctor for the Color struct.
