Bug reports: A possible bug?

Hi,
I am starting with Flint, it's nice the way how this works.
I picked this as base to make my version: http://flintparticles.org/examples/sparkler
The particles works nice, but when I made a simple adjust:
[code]
addInitializer( new ColorInit( 0xFF0000, 0xFFFFCC00 ) );
[/code]
When I just changed the first color as showed above, the particles doesn't works anymore.
Just works when I put the first color as the same of showed in example.
Why this happens? How I can get more colors as I need into this particle?
Thanks.

The colors are 32bit ARGB values - the first FF is the alpha value. So you probably want

addInitializer( new ColorInit( 0xFFFF0000, 0xFFFFCC00 ) );
