For ice or other usage.
I don't know if they look like ice cubes, but hopefully they do. Here they are on both a light & dark background, as they're slightly transparent:

You can give the [transparent cubes] a duo color effect by making 2 layers: a light color on top, & a copy of that layer with a darker color on bottom:

Hope you in the northern hemisphere keep cool this summer, and those elsewhere stay warm!
