Directly behind my computer's screen stands the sole red wall in my room. Though the wall stands stolid and silent, as any inanimate object ought to, it speaks. It brings warm, intense feelings upon my chest, inside my diaphragm, down to my toes. Silent, yes, but the thoughts and feelings it triggers mean far more then the spectrum of light my eyes perceive from it.

On the other three walls, a cool, calm blue with silver tones bring my mind to ease. For as long as I remember, blue has been my happy color, my favorite color. When I began to think about it, the reasons clicked.
Being a hot-headed person, blue has always centered me. It's the tone contrary to my personality; calming, seemingly melodic. It brings balance; it's the left to my right, hot to my cold, yin to my yang.

Studies have shown a direct and common correlation between color and blood-pressure. For example, when a test subject was shown the color blue, after relaxing for ten minutes, there was a measurable decrease to the subject's blood-pressure. Inversely, when a subject under identical circumstances was shown the color red in place of blue, there was a measurable increase in the subject's blood pressure. The color red both boosts blood-pressure and heart rate in parallel. Red is also commonly linked with feelings of sexual desire or interest, as our minds connect red with flattery, like the blush that emerges on our cheeks.

Colors are an intricate part of our lives. Subconsciously, our minds are perceiving and computing messages, feelings, emotions, and even moods. Although many don't take the slightest conscious notice, colors speak to us constantly.
