Suggested future work:
* Relate each colour to a brightness, hue and saturation URI. Maybe also
link to RDF documents for the combinations of b+h, n+s and h+s so people
can see variants of saturation, brightness and hue.
* Link to the complimentary colour (inverse)
* Link to the harmonious colours
* Link to the nearest 'web safe' colour.
* Give all colours a label, even if it's just the label for the nearest
web safe color. If
http://linkedopencolors.appspot.com/color/rgb/85a3ce.rdf said 'light
blue' somewhere it would have far more utility.
* Define some useful predicates; for example to relate an image to the
major colour(s) used within it.
* provide a .png as well as .rdf and .html so people can link to a
swatch of the colour.
* provide a recommended way to indicate transparency (which is possibly
separate from colour?) Perhaps also other properties like reflectivity etc.
Anyhow, I've knocked up a quick image-to-RDF service;
http://graphite.ecs.soton.ac.uk/img2rdf/
Example output: http://is.gd/3h0Ais
I've limited it to 10K pixels for now. Code available on request.

Thank you for this - very useful. Also very timely as OS are about to release all raster mapping products in RDF.
That's about time! I want to use SPARQL CONSTRUCT for image processing.
Best,

Hi,
for giving some color to the semantic web folks, we are happy to
announce the release the "Linked Open Colors" dataset [1]. The Linked
Open Colors project offers tons of facts about colors, all readily
available as Linked Open Data, linking with other relevant datasets
such as dbpedia.
The dataset and its publication mechanisms have been pedantically
checked, and we expect no errors in the triples; if you do find some,
please let us know.
This project is highly inspired by Linked Open Numbers project [2].
Happy April Fools' Day!
Cheers,
