Shifting/blurring material between objects

Question

I have a feeling this question is either trivial or impossible, but I don't have the blender knowledge to know which. I have 3 planes all of which share the same material, as shown in the picture below:

The colour is determined by a the random output from object info put through a wave texture and ColorRamp, so that I can randomly change the colours on the different areas by changing the Wave Texture parameters.

I would like to produce an element of blur between these objects. I would prefer real blur, that is an averaging of two neighbouring colours shifted by an amount in space, but if that's impossible I'd settle for a noise/vector curves method, I'm just not sure if that's possible here either.

Thanks, and sorry if this is a really dumb question.

See https://blender.stackexchange.com/questions/10453/how-can-you-smooth-the-edge-between-two-materials and https://blender.stackexchange.com/questions/49914/smooth-transition-between-2-materials You can't smooth between materials, you can't smooth between faces, even less so between different objects. Either do it in post-production, or use a different coloring technique that can be achieved with a single material — Duarte Farrajota Ramos, Feb 05 '20 at 10:24

In your ColorRamp node you can set the mode from "constant" to "linear", then add as many control points as you need to get the desired "blurring".

Thanks Josh but the random number coming from the object is a single number for the entire plane. When I feed that into the colorramp it will apply a single colour, regardless of how graduated the ramp is. – DoctorOrrery Feb 05 '20 at 11:59
