I found a beautiful site where your assigned sun sign and chakra association meet. very interesting, enjoy!
Aries
Aries is associated with the Manipura, or solar chakra. Located right under the ribs and traditionally visualized as being yellow, the solar chakra is the center of self-confidence, power and charisma. If those qualities sound familiar to the charming Ram, it's no surprise!
Taurus
Sexy Taurus is all about the Swadisthana, or sexual chakra, which has to do with sociability and, of course, sexuality. Colored orange and located just behind the pelvic bone, this chakra helps make the Bull particularly good at the fine art of seduction.
Gemini
Muladhara, or the root chakra, is Gemini's special spot. Located at the perineum, near the tailbone, the root chakra is red, and is a center for physical energy, control and stability. The Twins, of course, are always seeking stability.
Cancer
Cancer's chakra is the Muladhara, the root chakra. This red-colored energy center, located at the perineum, near the tailbone, is all about physical energy, control and stability -- all issues sensitive Cancer is deeply concerned with.
Leo
Leo is always one sexy sign, with their fiery spirit and go-get-it attitude. So it's no surprise to anyone who's ever loved a Leo that the Swadisthana, or sexual chakra, is the chakra the Lion is associated with. Colored orange and located just behind the pelvic bone, the Swadisthana is the center for sociability and sexuality.
Virgo
Virgo's chakra is the Manipura, or solar chakra. Located right under the ribs and traditionally visualized as being yellow, the solar chakra is the center of self-confidence, power and charisma -- not too surprising for a grounded, powerful sign like Virgo.

Balanced Libra is, naturally, deeply concerned with the processes of giving and receiving love.
