Is there vape juice out there that produces colorful smoke?

Regrettably, there are currently no electronic cigarette oils available on the market that can directly produce colored smoke.
Regardless of the color of the e-liquid itself, the resulting smoke is almost always white or grayish-white. This is related to the vaporization principle of electronic cigarettes. In simple terms:
??️ Why is the smoke always white?
The main components of e-cigarette oil are propylene glycol (PG) and vegetable glycerin (VG), which are inherently colorless and transparent. When heated and vaporized, they form tiny droplet particles. These particles act like prisms, uniformly scattering all wavelengths of visible light, and when mixed together, they appear white or grayish-white. This is the same reason why clouds are white.
⚠️ How do those colored smoke particles come about?
The colored smoke you see online might originate from these situations, each of which poses significant safety risks:
Visual illusion caused by light: This is the most common reason. For instance, the color emitted by the smoke itself, the colored lights on the equipment, special backgrounds or post-production effects, all these can make the smoke appear to be "colored".
2. Adding Colorants - Extremely Dangerous! : This is something that must be strictly avoided. Some patented technologies attempt to add colorants to create colored smoke, but this has not been commercialized. Never try adding food colorants to the e-liquid. There is no evidence to suggest that these substances are safe when heated and inhaled.
3. Natural oxidation causing color change of the smoke oil: This affects the color of the smoke oil itself, while the smoke remains white. For instance, after opening, the smoke oil will gradually darken due to nicotine oxidation. Exposure to light and heat will also accelerate this process.
??️ Safety always comes first.
Producing colored smoke requires the addition of pigments, but this poses significant health risks, so it is strictly prohibited:
Health risk: Safe pigments in food, when heated and vaporized, may produce toxic substances that directly harm the lungs.
Regulatory Prohibition: Both the Chinese national standards and the major markets in Europe and America prohibit the addition of pigments and other components in e-liquid.
Usage risks: Attempting to add colorants may damage the equipment, and there are no genuine products available on the market that can produce colored smoke.
If you have any questions regarding the ingredients of e-liquid, safety standards, or other aspects, I would be more than happy to continue answering them for you.
