The flag of Libra uses the colours soft lime green, pink, indigo and black. The pink and indigo stripes represent a balance between opposites since red and blue form the beginning and ending of color spectrum. They are given a lighter pastel shading which represents a delicate balance. Likewise they reflect the balance between male and female energies - pink representing feminine energy and blue representing male energy.
Since there are new 'planetary bodies' in our local solar system, Libra can finally get her own heavenly body. The best match is with the dwarf planet Vesta.
