The sample script being used (ObiPropertyColorizer) makes use of unity's animation curves, whose Evaluate() method only takes values between 0 and 1.
A value of 1 for diffusion is extremely large, so it will cause diffusion to overshoot (keep in mind that diffusion is time-dependent, and so subject to cfl stability conditions). The overshot diffused values will then go way beyond the 0-1 range, and since the sample script does not check for this----> error.
Just use a much smaller diffusion value, for instance 0.005. If you need very high diffusion values, you'll need to reduce your simulation's timestep size.
Checking for a valid 0-1 range in the sample script would make the error in the console go away, but still the fluid colors would vary wildly due to the high diffusion.
