Animate between two colors

[fgnass]

Unfortunately rgba() colors are not supported in VML and (in contrast to opacity changes) color animations are not hardware-accelerated in current browsers. Anyway, I'll keep your feature request in mind for the next version. In the meantime: What about using {shadow: true, color: '#fff'} as workaround?

With shadow, it just looks blurry and then lags like crazy. However, I figured since I'm already manually choosing whether or not to use my dark or light .gif files, I thought I'd just see what it takes to make this work for me.

You can see that by passing in white or black color at the right time, I can perfectly replicate the effect of the images I'm used to. The only downside is on non-white-or-black backgrounds, but to be honest, for those it's not about replicating the .gif look, because those always looked a bit funny the way they are. So now I think with a bit of tinkering and some input from my design peeps, I might get a nice effect. Just for kicks, I tried white and black with the opposition black and white 1px borders. Not a bad look!

I'm hopeful I'll be able to get this working in a happy way all over my site soon. I'll give it my best shot :) If color animations can't be hardware accelerated, it's probably not even worth bothering considering how much these spinners already tax the CPU. Sure my test has 8 of them running at the same time, and hopefully I'll only ever at most use 2 on a page at once, but still it's a noticeable difference so to lose any more performance might not be worth the bother.
