There's a story the Dice Goblins at Ice Cream Dice like to tell about a sea of rainbows from a far away land that would crash in waves of color against the shore splashing everything on the shore with a variety of colors.
They asked me to send out a search mission for this Rainbow Sea and, if found, place some dice on the shore.
The search mission was successful and we found the Rainbow Sea. We placed some dice upon the shore and these sets are the result of that experiment.
Please note: the splatter effect on these dice is achieved by painting them, so there is a bit of a rough surface wherever the paint is.
