I was retrieving the colors for an Enum attribute and noticed that if one(or more) of the colors are pure white, GetColor(...) will throw a NullReferenceException. This feels very odd since there is no way of preventing it besides not using white for any Enum value.

I would like you to either:

1. Return white when the color is white.
2. Overload the HasColor method so that you can set a default color yourself (without a try-catch).

IswAttributeType verdictType = SWConnection.Instance.Broker.AttributeType("EnumSID");
Dictionary<string, Color> colors = new Dictionary<string, Color>();
foreach(string str in verdictType.RangeArray)
{
    colors.Add(str, verdictType.GetColor(str));
}

Should probably mention that I meant overload HasColor to accept a string. This way you could call it for each individual value in the RangeArray.
