Random Color in objects using ProRender I am creating several objects and I want each of them to have different colors based on a color spectrum. To do so in the Shading tab I select all the objects and assign them a material. I then connect the Principled BSDF node with ColorRamp. Since I am using ProRender I do not have the Object Info input. Therefore I have using the RPR Lookup with Random Color selected. I then connect RPR Lookup to ColorRamp. In ColorRamp I selected three colors, Red, Cyan, and Blue. However, on the objects instead of showing any of these colors on each of the objects it only shows white. 

What did I do wrong? 

Thank you.

The &quot;Random Color&quot; already produces a color, not a random numeric value like the missing Object Info node, so I think it doesn't play well with the ColorRamp node.
If I connect the &quot;Random Color&quot; output of the RPR Lookup node directly to Base Color on Principled BSDF, I get random colors as expected.

If you'd like to get back the palette control that ColorRamp offers you, you can pass the output of &quot;Random Color&quot; into the &quot;RGB to BW&quot; node (found under Converter) and then pass that output into ColorRamp as shown below.
