Higher quality manga use special toning techniques with pen and ink or stick-ons to hatch in large areas, to create sense of depth, and for areas with repeated motifs, assuming they are drawing manually.
The pen types play a role too.
Hoshino Katsura (D-grayman) uses Zebra's G pen and Maru pen 丸ペン for nib/dib pens.
Ink is Kaimei brand's Sumi no Hana 開明-墨の華.

MC Escher uses mostly patterns in his work and is one of the most famous artists for using this technique.
Artists might use optical color when they want to create vibrant visual effects by placing colors side by side, allowing the viewer's eye to blend them from a distance. This technique enhances the luminosity and vibrancy of the artwork, as seen in Impressionist and Pointillist styles. By relying on the viewer's perception rather than mixing pigments physically, artists can achieve a more dynamic and engaging composition. Furthermore, optical color can evoke emotional responses and deepen the overall impact of the artwork.
