#Dressgate May have become loose – Aftonbladet

You might be thinking “oh no, not the dress again.”

But yeah.

Where the blue-black or white and gold?

The question that occupied half the Internet last winter has finally received a serious answer.

When the Scottish singer Caitlin McNeill presented last winter out a picture of the striped dress on the internet for general assessment of its real colors, she created #Dressgate.

Traditional media latched onto the snack ice: Be the garment blue-black or gold and white? Or maybe blåbrunt?

Now, research teams tackled the riddle, writes the news agency TT.

They have reached similar conclusions about how daylight and artificial light can affect individuals differently.

– Do you see colors the same way as me? The answer is sometimes no, says brain researcher Bevil Conway at Wellesley College in the US to Science News.



Light underlying cause

He connects different color perception to the type of light that the individual’s brain expects in the current environment. They just exposed to natural daylight tended to see the dress guldvit, while those who spent the most time in artificial light leaning more towards blue-black.

The changing light during the day, from red to blue to red again (rough expressed), also play.

– Your visual system must decide to reduce the shorter blue wavelengths of light or the longer redder wavelengths and that decision can affect how you see the dresses with colors, says Bevil Conway.

Much research

Seeing constantly trying to compensate for light shifts by carving out certain colors. Some ignore the blue and then see the dress guldvit and vice versa.

The psychologist Karl Gegenfurtner at Giessen University in Germany and his colleagues also found that the changing color perceptions depend on how the eye interprets natural daylight.
