I have brewed 2 batches of beer from kits, the first was a Corona style
Mexican beer and the second was Cooper's Australian Lager. Contrary to the
pictures on the kits both beers turned out to be a dark amber color. I was
advised by my local home brew shop that I would never achieve a light golden
color using kits but instead would have to brew with all-grain. Is this a
true statement? If not, does anyone have any ideas on what the problem might
be? I'm very new to home brewing and I'm not sure if I'm ready to make the
leap to all-grain brewing yet.

Thank you for your assistance.
