Q:

Color Chart Rosetta Stone

After discovering disparities between LEGO color names and families and 3rd party sites, I attempted to compile a sort of Rosetta Stone for the colors. Certain this is not complete but I believe a good start. Hope it helps. https://lego.pandorasdigitalbox.com/lego_color_rosetta.php
Any construtive ideas on how to improve it, or simple help completing it would be greatly appreciated.  Any suggestions or experiences you’d like to share would be welcomed too.

A:

You can look for missing data in currently available lists:
Old school Peeron (no longer updated)
Bricklink list most of the brick colors available for sale.
Rebrickable has attempted to bring all colors in one place.
Brickset has also some details.
Mecabricks has one also (as PDF).
LDraw project has such list.
It would also be good to define term "LEGO color". Is it for everything released by TLG or just the bricks with LEGO logo on them?
Last thing to note. People still keep finding genuine LEGO bricks made in officially not produced colors. So it is hard to mantain a complete list.
There are few people obsessed with LEGO colors, including Ryan Howerter. He has compiled a list of colors and details around them. If you wish to see these parts and participate in discussion you can get over to Ryan's Flickr picture gallery.
