the Darkest Day of the Year (2020)
"I'll stop wearing black when they make a darker color."
~Wednesday Addams (1938)
When 50 shades of grey just won't do ... Like its 2014 predecessor Vantablack, a cutting-edge pigment which used carbon nano-tubes, the newer blackest of all blacks, are material coatings, with light-absorbing capabilities that eliminates any perceptible dimensions on an object! Want an all black tartan? This particular tartan's pattern is made by different weaving and twisting techniques of the same color threads, which causes the light to reflect differently - pictorially, the pattern is represented by a lighter shade to illustrate. Today marks the earliest sunset of the year, which occurs before the solstice, the shortest period of daylight.When 50 shades of grey just won't do ... Today marks the earliest sunset of the year, which occurs before the winter solstice, the shortest period of daylight. Like the previous blackest of all pigments, Vantablack, a 2014 cutting-edge pigment which used carbon nano-tubes, the newer black pigments, are special material coatings, with light-absorbing capabilities that eliminate any perceptible dimensions on an object! Want to impress with an all black tartan? This particular tartan's pattern is made not with different color threads, but by different weaving and twisting techniques of the same color threads, which causes the light to reflect differently. Pictorially, the pattern is represented by a lighter shade solely for illustration.
Although the Winter Solstice on December 21st has the shortest period of daylight measured from ssnset to sunrise, the day of the earliest sunset, the Darkest Day, occurs earlier, on or around December 8th, depending on your latitude. Because of a discrepancy between our modern-day timekeeping methods and the fact that a real solar day is not exactly 24 hours, there is a significant variation.
On most days, solar noon does not occur at the same time as noon on your watch. Around the solstices, solar noon occurs a few minutes later than the previous day. For example, on December 21, 2018, the day of the Northern Hemisphere winter solstice, solar noon in New York will be at 11:54 am EST. On January 3, 2019, the day of the latest sunrise, solar noon will take place 6 minutes later at Noon EST.
As solar noons increasingly occur later, sunrises and sunsets also steadily occur later each day after the winter solstice. This is why a location's earliest sunset occurs before, and its latest sunrise occurs after the winter solstice.
A tartan worthy of the Darkest Day is one of the most black tartans available, Dark Island. Shown here with a grey weave only to illustrate the patterning, in actuality this tartan is woven in a different way from a conventional tartan. An ecru yarn is woven on a Jacquard loom with the sett being formed by stitches other than the normal twill. Then the finished fabric is piece-dyed black.
Shown here, the patterning stitches are illustrated in grey so as to be discernible. But in the actual fabric, the sett is highlighted because of the differing light reflecting qualities of the stitches on the actual materials, creating a tartan pattern with all black.
This new category of tartan is called a "Solid Sett" - a solid colour but with a sett still showing.
The Dark Island tartan has become popularly available for kilts as one of the newer "black on black" tartans (Freedom of Scotland being another, with Ben Dubh a close cousin with its black and dark blue-grey colours).
