Poseidonia M2503-4 is a Tres Tintas wall mural from the Méditerranéen collection, designed by Lázaro Rosa-Violán, in grey and white. Long, blade-like leaves shown as cut white paper layered in low relief, white on white.

The name is that of Posidonia, the seagrass of the Mediterranean seabed, whose long blades the design shows. The strokes are large, so it reads as one strong gesture. Made in Barcelona and printed to order.
