Color By Speed Module

The color of a particle can be set here to change according to its speed in distance units per second.

Properties

Property: Function:
Color The color gradient of a particle defined over a speed range.
Speed Range The low and high ends of the speed range to which the color gradient is mapped (speeds outside the range will map to the end points of the gradient).

Details

Burning or glowing particles, such as sparks, will tend to burn more brightly when they move quickly through the air (being exposed to more oxygen) but then dim slightly as they slow down. To simulate this, you might use Color By Speed with a gradient that has white at the upper end of the speed range and red at the lower end.
