While that ain't exactly the color of my aura, YMMV:
"Yellows are the most fun-loving, free-spirited, energetic, and childlike personalities in the aura spectrum. Yellows are wonderful, sensitive, optimistic beings, whose life purpose is to bring joy to people, to have fun, and to help heal the planet.
Yellows can either be very shy and sensitive, or they can be the life of the party. These playful characters have a great sense of humor. They love to laugh and to make others laugh. Yellows believe life is to be enjoyed. They like to live life freely and spontaneously. With a perpetual smile on their face, they remind people to not take themselves or their problems too seriously.
Yellows would prefer not to work at all, unless their work was fun, playful, or creative. They love nature, and often have concerns for the survival of wildlife and the environment. Dogs are very drawn to Yellows and often become their best friends."
.... be hard for a jig to live up to that, but sounds just like you imagine JOAT, doesn't it?
