So your article really helped. Here is my realisation. https://artmight.com/gallery/color/(color)/117/120 (yellow and green) with 50k images :) I'm currently indexing another site with 260k images. Will see how it performs. Source code of multi color search can be found here https://code.google.com/p/hppg/ I have chosen different database design and used Mysql partitions by color. To avoid file sort memory engine was used. Anyway everything can be found in svn of project. Also I have some ideas how to make search by color and keyword at the same time.

I had the same approach to image color search in my mind searching for class'es which could do the trick, when i stumpled upon this great article! If you're willing to expose some of your code in some way, that would be really great! Perhaps it could help a lot others struggling with image color search among huge amounts of images and even better you would get qualified feedback. Thanks again for sharing your thoughts!

I've had a go at implementing your algorithm in Rails with some tweaks as mentioned below 1) Use a palette of #xyz where each of x,y,z are in 0..F - this means I can make finding the closest root mean square faster as I know I only have to check the closest matching values. 2) I chose not to have multiple tables for the colors, but instead to have a table called color tokens whose field name was the color (e.g. F00 for red) 3) Instead of multiplying values directly, I used logarithms - log (AB) = log (A) + log(B). This keeps the numbers much smaller and reduces the risk of overflow - it also means I could effectively multiply tens of columns together. As a working example see https://www.tripodtravel.co.nz/palette/similar-to/4430610943/10 - there are only 17000 images there but it is enough I think to see that the algorithm is basically working Cheers, and thanks for the motivation :) Gordon hi Matt

Thanks for the article, came upon it by random chance. I’ve had a go at implementing your algorithm in Rails with some tweaks as mentioned below
