Dunno what to tell you autists arguing other than "works on my machine"
On the left, is the multiple meshes with Shadows/toon ramp
On the 2nd to left is 1 mesh with shadows/toonramp
3rd from left is 1 mesh no shadows
Last one is the most optimized since it has no color
[spoiler]That's a fucking joke by the way it not only has some color left but that's stupid to think[/spoiler]

Works on my machine, maybe your monitor has washed out colors, try going to https://www.eizo.be/monitor-test/
Or maybe http://www.lagom.nl/lcd-test/
These are some very good resources to get started in setting up your monitor for color accuracy!
