Map Xylography Blue is a Tres Tintas wallpaper from the Playful layers collection, in blue and grey. Irregular patches of solid colour, like islands on a chart, laid over a fine network of contour lines on a textured ground.

Xylography is wood engraving, and the patches carry a printed, woodcut grain. From across a room they read as a bold spot; the map lines show up close. Made in Barcelona and printed to order.
