It’s subconscious it’s not something you can learn. If that were the case people would have no issue understanding how others weren’t ‘decrypting’ the photo.

Also the majority see it as blue and black. 30% as white and gold.

The Journal of Vision, a scientific journal about vision research, announced in March 2015 that a special issue about the dress would be published with the title A Dress Rehearsal for Vision Science.

The first large-scale scientific study on the dress was published in Current Biology three months after the image went viral. The study, which involved 1,400 respondents, found that 57 per cent saw the dress as blue and black, 30 per cent saw it as white and gold, 11 per cent saw it as blue and brown, and two per cent reported it as “other”. Women and older people disproportionately saw the dress as white and gold. The researchers further found that, if the dress was shown in artificial yellow-coloured lighting, almost all respondents saw the dress as black and blue, while they saw it as white and gold if the simulated lighting had a blue bias.

Another study in the Journal of Vision, by Pascal Wallisch, found that people who were early risers were more likely to think the dress was lit by natural light, perceiving it as white and gold, and that “night owls” saw the dress as blue and black.

A study carried out by Schlaffke et al. reported that individuals who saw the dress as white and gold showed increased activity in the frontal and parietal regions of the brain. These areas are thought to be critical in higher cognition activities such as top-down modulation in visual perception
