Density

To obtain dark smoke effects, increase this value.
This value controls the overall transparency of the atmospheric effect. A value of 0
means that every single puff will be 100% transparent. Higher values will make the
volumetric effect more dense.
Keep in mind that low density values may have a huge impact on render time. The
puff’s density is calculated according to several aspects of the effect. Each particle
in the particle system generates a puff and each puff adds to the opacity of the
overall effect.
You can imagine the Density value as a global transparency controller for the puffs.
However, keep in mind that when you have just 100 particles with a high density, say
50%, you may well be able to see through this cloud. Increasing the particle count,
while keeping them in the same-sized volume, would result in a denser cloud.
Color

For details on using gradients, look up ‘Using gradients’ in the index.
The Color gradient on the
Globals page controls the color
of the puffs.
The Color gradient controls the color of the puff. From left to right, the gradient
represents the inside to the outside of the puff. This gradient provides the base colors
for all calculations and must therefore be created and edited with some thought.
