It took me a while to find it, but here's where I showed the colors from Skenara and Pelmora.

It really does matter what paper or paper texture you use behind the color.
If you use plain white, it loses a lot.
And all color layers need to be some form of transparent - in effect - multiply, color burn, overlay, softlight, etc.
So the paper texture underneath can show through.
So no opaque color layers.

Unless you are working in reverse order...
where line work is the top layer.
In that case you would have all of you color layers and then you would put a texture layer over top of those and likely set it to multiply to get that feeling of paper texture.
That is usually harder to do but faster, and also more imprecise and prone to error.
