I’ve been hunting down some del.icio.us power users to try and learn some new techniques with the tool and they seem to be a bit trickier to track down. I did discover one cool feature from kikipedia that was completely new to me - you can store colour palettes!

The process uses an extension to the URL format - specify a protocol of “color:” instead of the usual “http:” - and then the rest of the URL is a comma separated list of six digit hex colour codes. Here is the URL for the palette shown above:

You’ll be prompted for a description and can add tags as normal.

This is a great feature but I could find no mention of it of the del.icio.us blog. I’d like to see ColourLovers add this functionality to their application too, and maybe integration with the Palette Grabber or ColorZilla Firefox extensions.

So, I found one hidden feature of del.icio.us, do you know of any more? Do you know of any applications that use del.icio.us to store colour palettes? I didn’t test with Adobe Kuler because I hate Flash applications. Comment below if you have anything to add!
