Additionally, real crystals may exhibit variations in their growth patterns and shapes, whereas ideal crystals would have uniform characteristics. **

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. **
