what you do is get a spray mister fill it with water, turn the shell or body upside down and spray water up into the air over the top of the shell,it then falls on the shell make sure you spray enough to form nice sizec water beads(say 2-4mm)then while the water is still wet you spray a dark colour from one side and stright after a lighter colour at the other, ether let it dry naturaly or dyr slowly as not to move the water around when the water invapourates it gives you a awsome water bead effect,like this
