Purple

Color purple contributes the stability of blue and the energy of red.
It's been associated with the royalty and it symbolizes power, nobility, luxury, wealth and extravance.
In other ways it is also related to wisdom, creativity, independence and dignity -that's the part I like the most.
Several surveys show purple is the favourite colour for the 75% of children before their adolescence.
Purple represents magic and mystery as well.
Pale purple brings us some nostalgic and romantic feelings, meanwhile dark purple evokes melancholy and sadness.

Purple is my favourite colour, followed by black.
