1. A single part reflective textured finish composition capable of forming a textured coating having a metallic appearance and a solar reflectance percentage, measured according to ASTM E1331-15, greater than or equal to 40; the reflective textured finish composition comprising:
a) at least one organic binder containing at least one polymer emulsion or dispersion;
b) at least one pigment; and
c) from 40 to 90% w/w of at least one aggregate including:
particles comprising at least 3% V/V of particles having a sphericity (SPHT) of less than or equal to 0.5; herein referred to as SPHT/0.5 particles, the % V/V being with respect to the whole content of particles; and/or
particles having a mean roundness (RDNS) that is equal to or less than 0.29; the particles being herein referred to as RDNS particles,
wherein the at least one aggregate comprises a glass aggregate.
