LEGO Techniques - All the Pretty Colors!

Ever been confused by TLG's color palette?  It's true, there are many colors that are similar.  Sometimes TLG updates a color and doesn't consider it new (as in blue) and sometimes they do (old light grey, new medium stone grey).  Sometimes colors are only used on specific items such as Momo from the Avatar sets; only known piece in light tan.  Or maybe you'd like an army green watch band piece?  Not dark green or olive green.

It's really a monumental task to understand all these colors, let alone organize them.  But AFOL eldeeem (Ryan) has gone through lengths to secure parts in EVERY color ever made and thoroughly catalog them.  The Resources page has been updated with links to a custom Flickr account and detailed spreadsheet.
