Help Color of my fluid

[Goulougalam]

Hello,

I got trouble trying to change the color of my fluid, 
the only way i found, for the moment, is to enable "render" on the component "ObiParticuleRenderer" but after I got of course a visual with lof of spheres for my particules,
So I don't arrive to find a way to keep the render of a fluid but opaque and with the color I want.

Thanks in advance
