I would like to create a class that, when I call without the double brackets, returns a value in any context, just like what str or int does. For example, what can I do to make this possible:

>>> class color:
...     def __init__(self, r, g, b):
...         self.r = r
...         self.g = g
...         self.b = b
...     def whatever_it_is(self):
...         return (self.r, self.g, self.b) # Class returns tuple
>>> myColor = color(16, 32, 64)
>>> myColor.g
32
>>> myColor
(16, 32, 64)
>>> color(5, 68, 37)
(5, 68, 37)
