For most people, fictional novels are a welcome escape from reality- a journey that is at once peaceful and enthralling. These books are not usually a method to further grind our brains. That can be accomplished on a regular basis simply by stepping outside the front door. Therefore it comes as no surprise that the first thought to cross our minds during one of these heavenly respites is not usually the accuracy of the horticulture encompassing the setting, or the length of the hero's coattails, or the underlying symbolism behind the hue of the lady's gown. How many authors really stop to consider this factor as they meticulously weave together the threads of a scene? It's hard to say for sure. Even if this factor was not intentional or even taken into consideration by these talented writers doesn't stop us from considering the correlation ourselves.
As far back as ancient Egypt the concept of color psychology has played a role in culture and evolution. For centuries the color purple has been revered as a symbol of royalty. White is still today identified as a beacon of peace. Therefore is it really a far stretch to consider a character's personality in correlation with their setting or their attire? Perhaps that red gown a particularly feisty heroine is draped in is a nod to her strength of heart. Maybe that blue overcoat a handsome lord decided on for the evening hints at his reliability. Though much time has passed since the original discovery of this theory the study of color has only grown in popularity. As with many similar beliefs, it has yet to be agreed upon how much truth the study holds. Below I have placed a link with further information on this unique science.
