The Tiger Is Only Orange to Us
A saved tweet claimed that a tiger's famous orange is a kind of accident of the viewer: to a deer, the same coat reads as green.

A saved tweet claimed that a tiger's famous orange is a kind of accident of the viewer: to a deer, the same coat reads as green. Five days later, a Saturday in Ratoath put an actual tiger in front of the idea. The question walked around the enclosure all afternoon: what exactly are we looking at when we look at that colour?
A fact worth testing
It started as one of those saved posts that lodges in the head: "Tigers look orange to humans because we are trichromats, but they appear green to deer and wild boars because they are dichromats" [1]. The camouflage is not for us. We are the only ones in the forest getting the full show.

Then, an actual tiger
At the park the tiger was doing ordinary tiger things, pacing its enclosure among the trees and barrels [2], then batting a blue toy barrel around like an oversized housecat [3]. Against the grass and the water feature, the orange is almost absurdly loud [4]. A cheetah in the next enclosure made the contrast sharper: built for the chase, coloured to disappear [5]. The tiger, to human eyes, is coloured to be found. Some shots came through reflective glass, enrichment toys and rocks doubled in the pane [6], which felt fitting, the whole visit was about how much the viewer changes the view.

What the deer never sees
The last photo is the tiger at rest behind a metal fence [7], all that orange laid out in the open. To a boar walking past, this would be a patch of green among green. The tweet stopped being trivia and became a caption for the whole afternoon: the most conspicuous animal in the park is, to the eyes that matter, invisible.

One saved fact, one Saturday, one tiger. The orange that fills every photo is a colour the tiger's prey has never seen, which means these pictures show something only humans get to see.
