This story was originally written in Spanish for "Antología de colores (sin colores)" (Anthology of Colours (Without Colours)). It was a contest that required to inspire a colour without mentioning it. That's why its reading is also a game where you have to guess the colour the writer had in mind.

If you want to play with the anthology rules and you can read in Spanish, I recommend you reading it in its original form. This version is enhanced with visual effects that may give you hints about the colour. You can download it for free and thus find other tales that are worthy of your time.
