Finding Colours
Wacky idea last evening:
A program that uses natural language colour names as an input. An internet agent then goes looking for representations of that colour in the wild, takes the average of all of them and returns the definition to the user.
It kinda works already: check out lindgrün (pastel green) or petrol green. Of course – to work properly, this would require the real Semantic Web, without that, there always will be a lot of rubbish between the actual colour samples.
