Random color per object

I know you can get random color per instance, but it would be very useful if it was possible to get a random color for any object in the scene, like redshift and arnold can do, to use for texture offsets or color offsets. There is a workaround to use mograph but that is not always practical.
Is there any way to do this in OSL?

Hi,
you can do it also with c4doctane, with a couple of clicks.
Select all the desired objects, apply an Octane Object tag, and enter
num in the Instance ID field, to assign a different sequential number to each object.
Then use the Instance Range node to pilot a gradient, or an OSL random projection node:

Great tip, thanks!
But where is the OSL random projection node? Can only see 'OSLProjection' which doesn't seem to do much...
