Crystal violet lactone is colorless because its molecular structure is in a closed lactone form, which does not absorb visible light. When crystal violet lactone is exposed to an acidic environment, it undergoes a chemical reaction that opens up the lactone ring, forming the colored crystal violet dye. In this open form, the molecule is able to absorb certain wavelengths of light, giving it a violet color. Therefore, the color difference between crystal violet lactone and crystal violet is due to the structural change and resulting ability to absorb light in the visible spectrum. **

The UV tube glows weakly violet because it emits ultraviolet light, which is not visible to the human eye. However, a small amount of visible light is also emitted as a byproduct of the UV light production process.

The weak violet glow is a result of the combination of the UV light and the small amount of visible light being emitted. **
