[visionlist] An On-Line Color Thesaurus

[Nathan Moroney]

Hi all,

We recently posted an on-line color thesaurus that some of you
might find interesting:

http://h20325.www2.hp.com/blogs/color/archive/2007/10/29/4914.html

This web tool uses patterns of natural language usage for
unconstrained color naming as collected from 3,000+ partcipants
online to infer an 800+ color name "vocabulary".

The synonym computations were relatively straightforward (nearest
4 names greater than a threshold with some assumptions) but the
antonyms were not. I won't try to cover the specifics of what I
did to calculate color antonyms in this email but I would appreciate
any references or feedback about current understandings of perceptual
opponency and linguistic "opponency" and how they interrelate.

Thanks in advance and best regards,

Nathan Moroney
