Today is my birthday. I found this fun thing on Pantone. The people who bring us the color trends each year. This is Colorstrology. It gives the color that is represented by your day. Kinda cool and you can order the whole year, too.
This is what Ocotber the 13th says-
Color-Opal Blue-According to the website "This is my personal color that pertains to the real me"
Practical, Builder, Driven
"You are capable of handling huge amounts of responsibility. You can work tirelessly as long as you can see the fruits of your labor. Although you can do things very well on your own, it is often better to align your objectives with others. Home and family are important to your well-being. Try to stay lighthearted and do not allow your goals to dictate all your waking hours. Wearing, meditating or surrounding yourself with Opal Blue helps lighten the serious side of your nature while promoting the realization of your dreams."
Try it and see what you color is.
