Sepia is the colour of nostalgia and the rustic, with the ability to transform even the most mundane and regular to something cool and retro by, what i consider, a plain induction of this mental frame that anything with a tea tinted gloss is right from the shelves of the distant past and hence, rationalizing and analysing this thought in the sub conscious, we infer that the photo was important enough to preserve against the transience of time and hence a bias gets hard wired in our mind that makes us review the pic from a non-neutral frame of view and hence the general consensus that sepias lend a better feel to the photo.
Thats why, happy and pleasant memories lack the natural vividness since our mind’s eye affords a view from a sepia-ed pane.
While on the other hand, we tend to remember the unpleasantness dissolved in the murkiness of our past explicitly with every detail in place, some, even made up…
So to condense the first assertion in this post and to attune it to some of the above arguments, i guess sepia is the colour of happiness, of longing and of the conspicuous absence of pain in the our nostalgia, when so often we get caught on the wrong foot, inundated by a brown surge, overpowered by the scent, it carries of the times gone by and a reminder of the proliferation of the cobwebs that play ‘the’ role in transformation of this image in our mind from an a’ la darjeeling to an a’ la assam and then on to even more profound shades that finally cloud and obliterate the details and in the end, the sepia, this colour of happy recollections proves its own undoing and reduces the image to a scene, youngly bereft of an erstwhile innate happiness……and since the absence of happiness translates to sadness, the sepia coalesces with the ‘true colour’. so with time, it all becomes excruciatingly uniform and repetitive…..and i…..well……….i revert back to the definition at the top of this post, as it retains its meaning even in the face of this onslaught of my random ramblings…
