In the comments to my original [topographic bookmarklet post](/posts/04/04/01/0), [Peter](/posts/04/04/01/0#21) suggested an improvement to give it sixteen height levels, rather than the original ten.
I tested it quickly, and sure enough it works, so if you find yourself hitting pink backgrounds on a few sites, you may want to update your bookmark.

[Jesse Ruderman][sf], who keeps an excellent repository of bookmarklets at [squarefree.com][sfb], offers a further improvement. This should be faster, but may not work in some browsers.
