About Alexandrite Color
Alexandrite is a rare color-change variety of chrysoberyl. Under daylight or fluorescent illumination it can appear green or bluish green, while incandescent light can shift the same stone toward brownish, purplish, or reddish tones. The transformation is so characteristic that comparable behavior in other gems is called the alexandrite effect.
No single HEX can represent Alexandrite honestly, because the defining feature is change across illuminants rather than one fixed surface color. The green reference on this page works as one daylight-oriented anchor. A fuller digital treatment would pair it with a red-purple state and explicitly label the simulated lighting condition.
This swatch is one digital interpretation, not a reproduction of color change, pleochroism, gemstone identity, origin, or value.
