Color:
Pantone.com - pantone is to a
designer as crayola is to a 5-year old.
Design:
Sitepoint.com - amazing resources
on webmastering and design, you can find me there bumming around the
forums.
CSS Zen Garden - A showcase
for CSS/table-less design. Great starting place if you want to dive
into CSS design.
Personal favorites:
Adam Polselli - Nice fellow
with a nice site/blog about design. Be sure to check out his "Get
the look" articles.
