Cattleya closes December on the 31st, paired with Turquoise Blue (#00AFCC) and the color word "a spring." Grace and charm remain the flower's meanings. The clear blue is an unexpected note at the end of the year — a window opening onto the next season.
The year closes under the brightest star there is: Sirius, alpha of Canis Majoris, magnitude −1.45, the 'scorching one' of the Greeks — just 8.6 light-years away, waltzing with a white dwarf companion. Passion and guidance are its star words, and right around the turn of the year it flashes fiercely at its highest in the south. The final color is Turquoise Blue (#00AFCC), read as spring water. The strongest light above, water welling up below: every ending doubles as a signpost.
The birthday fish of December 31 is the Grey mullet. Its fish words are "journey" and "fortitude". In the season when it fattens with the cold and is known as winter mullet, its roe, slowly dried into a treasured delicacy, has long graced felicitous tables, at its peak from December into January. The color of the day is Turquoise Blue (#00AFCC). With a radiance like clear spring water, softly open the door to the new year.
Dec 31 belongs to the Banpeiyu pomelo (晩白柚). Market stalls fill with this citrus fruit around Jan. The fruit words for this date read "generosity and quiet strength". Jan is its season. Its date also carries the birthday color Turquoise Blue (#00AFCC). The color word here is "a spring". One fruit, one color, one day.
