Thunder

Thunder is the colour of lightning in the darkest night sky: the shocking purple that stuns the sky for a millisecond.
It is a flabbergasting colour, the one that catches the eye third in a room of all colours, after the brightest red and white.  Often accompanied by a loud, deafening sound and followed by a shivering silence, it is pleasing to some and dissonant to the others. Some days, it also soothes, like a quiet, pondering colour, when found in the tips of orchids and in the skin of ripe aubergines. It could be disturbing in a fresh, deep bruise near the eye, and could be mesmerizing when found on the edges of a nebula, light years away. Mostly, it is dominated by and stuck between the near black and a vibrant violet, and often lost in the palate.
