It’s not candy. 😀
A silicon candy tray with various shapes, but only the square-edged pixelated heart shapes are filled in with what looks like a variety of colors.
A paper towel stained with a rainbow of colored dyes.

It’s LED pixel hearts! It’s just a standard silicone candy mold I got in the clearance aisle, filled with colored epoxy, and some LEDs stuck in it. These are designed to go on my LED Tree. https://dominionofawesome.com/vca/ledtree/

A green silicone candy mold, with colored epoxy in pixelated heart shapes. Popsicle sticks hold LEDs in place while the epoxy sets.

Finished building the tree. Sadly the camera doesn’t really do justice on the lights.
Partially built LED Tree project. The base circuit board is square with a green base color and white solder mask making a triangular pattern. At the front of the board is a USB type-C port. Sixteen resistors ring pairs of twisted wires in the center of the board. Not all of the wires are installed at this point, and you can see how they cross over each over for extra stability. Other components are missing (but this is intentional for this version of the design).
The rear side of the LED Tree, showing the rubber feet being added. The circuitry forms a ring. At the bottom of the circuit board it says “Made with <3”.
An overhead view of the tree with all of the wires installed. They have been bent into a shape that resembles a large deciduous tree with several forks coming off of its thick trunk. At the end of each wire is a two lead connector. A white pixel heart LED is inserted into one of the connectors.
The fully assembled tree with all LED pixel hearts inserted and they are lit in a fantastic array of colors. Some have swirls inside. Some look like gems with points of light in their centers. Others are diffuse and more uniformly lit.

Love it!

What the material you used for casting? Is it silicone?
