Blackmore wears Catch the Rainbow as a mask. A heavy supraorbital ridge of a vaguely troubled angle hangs over its eyeholes. It has no nose, and in the region of the mouth it bears a row of five long, vertical slits, dotted by five holes.
Light overall, it is marked by three colorful stripes crossing from its left eye to its right cheek. The stripes were designed to be a rainbow version of a hockey mask. 
Rain Manipulation: Catch the Rainbow allows its user to utilize or manipulate rain in various novel ways, such as stopping raindrops in their place and treading a path across them. If a target attempts to move through rain stopped by this Stand, the drops will tear and penetrate them.
Blackmore is seemingly able to meld with rain, becoming intangible like water and nigh invincible, and project various parts of his body out of raindrops, as if they were portals. Blackmore demonstrates the ability to plug his wounds with rain drops and stem all bleeding.
Crucially, this Stand is effective only when it rains.
- Along with being the Stand's namesake, the idea of walking on the rain comes from Catch the Rainbow.
