Color with falloff | Animation nodes 2.1 in blender 2.81a I have these squares that spin 90 degrees when the falloff passes over them, I want them to change color from blue to magenta at the same time, I've made this array to clone one and got the color to work but it's only effecting the first one since they are all using the same material. How do I do this?

I either want to color the emission node using the falloff 
OR
Change color along with the 90 degrees of rotation

Rendered in cycles

I would love some help with this! :)
You can make use of the "Viewport Color" property of each object, since this property can be accessed in any shader. 

See my answer here for more information : https://blender.stackexchange.com/a/163699/86891

In your animation node tree, you need to add an "Object Attribute Output" set to "color" :



Edit :

As of V 2.1.7, thanks to 3DSinghVFX there is a node specifically for this : The object color output.



Then access it in your shader :



These two objects share the same shader, but I am modifying the left one's color in my animation nodes tree :



In order to change each individual object's color, use this setup :



Don't forget to tweak the "Evaluate Fallof" node to output a list instead of just one value. You need to click on the button on the right of the "location" field in this node. Notice how it is blue tinted.
