  A candle having a selectively and reversibly variable color pattern. In one embodiment, the candle comprises a solid transparent gel with a thermochromic or photochromic pigment dispersed evenly throughout. The candle main body changes from a first color to a second color, or from colored to transparent, or from transparent to colored, in response to heat or light from the candle flame, and reverts to the original color or absence of color upon extinguishing the flame. The candle comprises (a) a solid combustible matrix, and (b) a reversible thermochromic or photochromic composition blended into said solid combustible matrix.

  一种具有可选择、可逆变色图案的蜡烛。在一个实施方案中，蜡烛由固体透明凝胶组成，凝胶中均匀地分散着热致变色或光致变色颜料。蜡烛主体在烛焰的热量或光线作用下，从第一种颜色变为第二种颜色，或从有色变为透明，或从透明变为有色，熄灭火焰后又恢复到原来的颜色或无色。蜡烛包括 (a) 固体可燃基体，和 (b) 混入所述固体可燃基体的可逆热致变色或光致变色组合物。
