You could use the fluid properties operator. Enable the velocity channel and give it a name, then in a mapping operator use the mapping from data and assign the velocity channel from the fluid operator. You can then use the mapping operator to drive the uvw of a material, such as a gradient ramp. You can renormalize the values in the mapping operator to adjust the blending values. Just make sure you set the timing on the mapping operator to continuous.
