Please someone show me how to achieve cell shading by using the compositor and without using ramped color materials. Since nodes are new to me it would be helpful to have a screen cap of the schematic of the node connections required and any additional information on how to set lamps and lighting if it is needed, also what should and should not be checked to allow anyone who wants to reproduce it obtain the same results. Do not refer to this link:
This page does not make it obvious what has to be done relevant to my request, it is a dead end to a noob who wants to understand as there are so many answers but none of them seem to be about affecting an entire scene, only materials.
I happily thought how fun would it be to make some cartoons with Blender. Connecting nodes... more like like pulling hair, no tutorial I follow exactly produces the same results described even when I copy an exact demonstration there is something probably not node related that keeps it from working.
The example below shows exactly what I want, cell shading in blue, highlights in yellow that is not gradual or granular. Textures get the same treatment and if I add an entire city to this scene it will also get the same cell shading. Nothing in this scene has any ramped or toon materials.
