Colorjoe - A Scaleable Color Picker (No Images)

Very nicely done. I attempted something like this a while ago but it didn't come out quite as nice.<p>I like that you decided to use some base64-packed images instead of using anything external; good idea.<p>You may want to include something about what browsers are supported. As it is, the page is completely broken and not usable with IE9 (1).<p>Nice work, though!<p>[1] - <a href="http://i.imgur.com/d7JFq.png" rel="nofollow">http://i.imgur.com/d7JFq.png</a>

How did color pickers like this become so popular in non-pro situations? They are completely impossible to use for mere mortals (for example, try and pick the same color twice).

Ah, I see, by "scaleable" you mean that it can literally be scaled to different sizes on the page. (For HN, an uncommon use of that word.)

Wow, very clever usage of overlapping semi-transparent gradients to get the square of saturation and brightness variations. Good job!<p>Too bad it isn't possible to draw color wheels in pure CSS, AFAIK...

Very clever. Unfortunately, the rounded corners aren't being drawn right here (Firefox 15a2 on Linux), there's blobs of colour being drawn.

Would be nice if there was an affordance for transparent, this is a common problem for JS color pickers I've seen recently.

It would be great if github used a color picker, instead of requiring manual hex input, for the issues label color picker.

i'm sure other people have mentioned but it doesn't work in IE9 or below. You should at the very lease support IE9. If you wanna throw away IE8 or below, it would make sense to just use canvas rather than a base64-encoded image.

Nice, was just looking for something like this. Thanks!

Looks nice. Are you planning to support IE&#60;9?

Wow, this works very well on Mobile Safari.

using opera 12 on win7 the cursor position isn't matching the color picker circle :(
