Parchment style is perhaps the most classic look of a fantasy map. The colours and texturing are created to evoke the feeling of an antiqued paper or parchment. The perfect map to accompany a classic medieval fantasy story.
Partial Colour Maps
Partial colour style mainly differs from parchment maps by colouring. It's more stylised than a full colour map, mainly consisting of two main colours - land and sea.
Full Colour Maps
Full colour maps are more complex than parchment or partial colour works. The colours are usually aimed to be a tad more realistic - blues for waters, greens for land, and different biomes are represented in different colours.
Every now and then I get to experiment with different styles and colours. Here you can see a few results of those experiments.
