Mesh and Fluid Problem

[sc00b]

How have you set up the diffusion values for both fluid types? Black should only appear when the fluids have very little or no diffusion, and both colors multiply each other without mixing (because as I pointed out before multiple times, when using multiplicative blending pink*green = black, green*red = black, as they're complementary colors).

Chemical A and Chemical B in the FluidMixing scene both have a diffusion of 0.002, and the diffusion data channels for chemical B are (1,0,0,0). Then this channel is mapped to a particle color using the gradient in ObiFluidPropertyColorizer as diffusion kicks in. Make sure your setup mimics this one.

I understand how your system works, but in life it’s not. In the gradient picture, it is shown that if you mix 50 to 50, you get a grayish tint. Here's how to get it? Change the script, but which one?

p.s. Yellow with red, it turns orange, but if you mix red and green you should get a different color, but definitely not black) understand?)
