Ok, so I was coding some stuff for naranai and I was thinking to myself that it’d be cool if I could automatically detect a few dominant colors in a picture and use it to make them searchable. To start off honestly, there aren’t many people doing too many things with PHP and color detection in images. I found a spiffy little class that gets me half-way where I want to be. That’s where the problem comes in! The color extract class gets me to a nice solid color, and it does rounding so I don’t get back 500 results.
So I get the sweet hex back and now I want a relative hue. You know? Brown, red, penis. So I start trying to look around for a list of rough hues and the RGB values relative to them. I didn’t have much luck, but lucky for me, someone had already done the legwork. The only minor issue was that it was JavaScript. SO WHAT DID I DO?!
I FIXED IT UP! Oh, as I side note, there are some color names I don’t necessarily agree with and I’ll fix them up over time. If there are any that you don’t agree with, add a comment. Yes this will be open source.

Update: I changed the code over so it uses an array rather than JSON stuff. Doesn’t see much faster, but apparently some idiots don’t install JSON support for PHP.
Awesome. I’ve always found it unwieldy to have a large collection of wallpapers – I remember what one looks like, or what’s the predominant colour, but I have no clue what its filename is. I would like to see more colour detection apps on the client’s side – I’d appreciate even a standalone application, although the best solution would be integrated into a file manager.
Yeah, someone really ought to put together something like that. Or maybe the John’s Background Switcher guy could roll it into his stuff.
Thing is, there are many more thorough image libraries on the desktop platform, so it’s odd that there’s nothing around. Or at least nothing popular enough to jump to mind.
And vista even has image tag support but nothing doin’ as for an app that tags stuff for you. Does Picasa have a search by color thing? Seems like they should.
