Can't see the flash preview thingy on the lower right. Can see the other ones. I've seen this before with flash in Firefox. Might be an interaction with the AdBlock extension, which can be uninstalled over my dead body. ;-)
When this happens on other sites, I just scroll down until the top of the flash item reaches the top of the browser, and then it displays. Can't use this workaround on your site, because there isn't any more content to scroll down to after that.
BTW I don't mean to complain! Nice looking site. I'm just assuming you were hoping for feedback, so there it is.
I like this - I agree w/bmaier that the visualization is great. Often what looks light at 20px square looks very dark on a full page.
One suggestion - right now I need to click around a lot to make changes. To change the bg, I click on the #1 box then head over to the slider, then to change the header, click on the #2 box and again head over to the slider... can you get that slider control to appear right on the page layout. That way I can go the section I want, see the slider, move it and then keep going...
very cool.. you consider adding features to let me download a stylesheet and maybe some preconfigured "skins"/"themes" instead of hacing to reconfigure 5 colors, just select one skin and have it being configured to set all 5 colors.
neat. Actually, I was fooling around with color layouts today. Just in case you haven't heard of it, I ran across Munsell color pickers, which lays out colors according to how people perceive color.
What I recognized as an itch is that color pictures and theme generators would actually be better as a FF plugin, so you can adjust entire color palettes and see it take effect right on the page you're working on.
Very nice. Suggestion: clicking an area in the Test Pattern should change the selection to that in the Color Palette. Or at least identify the Test Pattern swatches as corresponding to one of the numbers 1-5 in the Color Palette.
Otherwise, nifty tool.
