Depression and gray color
When you are depressed you say that you see everything gray. This metaphor has been studied by the University of Freiburg, by a group of researchers headed by the psychiatrist Ludger Tebartz Van Elst.
The group of researchers looked for the nexus between the depressedness and the gray color, concluding that the depression causes that the contrast between the black and white colors is diluted.
To reach that conclusion, the researchers used electrodes to record the electrical activity of the retina in response to a series of flashes. Depressed patients responded to the flashes with less contrast in the photoreceptor cells of the retina.
Thus, the metaphor of seeing everything gray is not entirely incorrect, since it is closely linked with the person's state.

Es una información muy interesante no me la sabia.
Por cierto el código que pusiste en numero 2 de la fuente esa es la manera correcta de hacerlo, es decir los dos métodos que te pase solo coloca el que mas te guste.
Ademas trata de interpretar la información a tu manera para que no tengas problemas de plagio y usa tag correctamente en este caso seria, blog,life,writing y quizás también el tag love, pero recuerda no copies y pegues todo tal cual esta en la fuente.
así seria la manera correcta, Saludos.
