Particle size distribution of beads, corn starch and Holi colours. Illustrated is the particle size distribution of commercially available beads of 2 µm, 3 µm and 6-6.4 µm (a), corn starch (b) and 4 different Holi colours (c-f). The gate P0.7-10µm indicates the percentage of particles bigger than the detection limit of 0.7 µm but smaller than 10 µm in diameter
