Cold pyro color smoke fireworks, also known as "cold spark color fountains," are a type of pyrotechnic effect that produces a fountain of colored sparks and smoke without the use of traditional flame or heat sources. They work using the same technology as cold pyro fireworks, but with the addition of colored pigments to create a colorful display.

The machines used for cold pyro color smoke fireworks are similar to sparkler machines, but they include a cartridge containing colored pigments that are released along with the sparks. When the electric current passes through the metal rod, it heats up the cartridge and releases the pigments, which mix with the sparks to create a colorful display.

Cold pyro color smoke fireworks are often used in indoor events and performances, such as concerts and theatrical productions, to create a visually stunning effect. They are considered safer than traditional pyrotechnics because they do not produce flames or heat, reducing the risk of fire or injury. However, it is still important to use caution when handling and operating cold pyro color smoke fireworks to ensure they are used safely and responsibly.
