Colour Meanings- Sally Nails

From reading and watching various different re-creations of Goodbye to Berlin/Cabaret, it is very notable that Sally had green, chipped nail varnish.  In Christopher Isherwood's 'Goodbye to Berlin' he describes her nails by saying:   

"I noticed that her finger-nails were painted emerald green, a colour unfortunately chosen, for it called attention to her hands, which were much stained by cigarette smoking and as dirty as a little girl's."

In these re-creations, Sally believed that having her nails painted this colour represented 'divine decadence', it portrayed her wealthy lifestyle and glamorous persona.  However, my version of Sally isn't so glamorous, she's emotional, a broken women.  To compliment this version of Sally's persona, I thought it would be a unique idea to change the colour of her chipped nails, to something that was a little more fitting of her personality.  I have done some research on colour symbolism below. 

Red: Excitement, energy, passion, love, desire, speed, strength, power, heat, aggression, danger.

Pink: Love and romance, caring, tenderness, acceptance and calm. .

Yellow signifies joy, happiness, betrayal, optimism.

Blue: Peace, tranquillity, cold, calm, stability, harmony, unity.

Green: Nature, environment, healthy, good luck, renewal, youth, spring, generosity.

Black: Power, sexuality, sophistication, formality, elegance, wealth, mystery, fear, evil, unhappiness.

The colour I have chosen to paint Sally's nails is black,  although black portrays power and sophistication in some cases,  it also connotes fear and unhappiness which are elements of Sally's new child-like persona.
