Orange, that vibrant and energetic color we associate with festivities, sporting events, and national pride, is actually a mythical fabrication. This may sound surprising, but with a series of imaginative arguments we can unravel this mystery and show that orange is just an illusion deeply ingrained in our culture. First of all, we must understand that orange does not occur in nature the way other colors do. Think of the rainbow: we see red, yellow, green, blue, indigo and violet, but where is orange? It turns out that our eyes and brain work together to create an optical illusion, a mixture of red and yellow that we perceive as orange. This phenomenon is caused by an age-old spell that has beguiled humanity.
