According to Stephen Juan, Ph.D., an anthropologist at the University of Sydney, there is much behavioral science research showing the most popular skin colour, eye colour, or hair colour in terms of sexual attractiveness. But there is little on what is the most sexually attractive color per se.

Different cultures have different attitudes and preferences in the attribution of qualities of colour and behaviour. For example, "black" is associated with death in European countries. But "white" is associated with death in China and "purple" is associated with death in Brazil.

As for sexual attractiveness, there is an enormous cultural component in this as well. Gender is another confounding variable. What might be perceived as a highly sexually attractive colour on a woman may not be perceived as such on a man. And what might be a highly sexually attractive colour to a woman may not be so to a man.

Nevertheless, drawing upon various studies from the fields of colour psychology and color therapy, a not-too-scientific ranking of "more" or "less" sexually attractive colors could be constructed from the list below of colors and there supposed attributes.
Black: Sophistication, elegance, seduction, mystery, sex, banishment, binding, protection, evil

Blue: Trust, reliability, belonging, coolness, tranquility, peace, calm, wisdom, justice, depression, understanding, patience, loyalty, sincerity, honour

Brown: Earthy, conservative, protective, constructive, hard-working, solid

Copper/Bronze: Love, passion, friendship, sex

Gold: Prestige, expensive, elite, authority

Green: Nature, fresh, cool, growth, abundance, rejuvenation, recovery, healing, harmony, balance, peace, hope, jealousy, envy

Grey: Neutrality, staleness, depression

Magenta: power, magnetism, spiritual power

Orange: Playfulness, warmth, vibrant, encouragement, luck, kindness, stimulation, optimism, abundance, success, independence, sensual

Pink: Soft, sweet, nurturance, security, tenderness, peace

Purple: Royal, spirituality, dignity, divination, inspiration, meditation, compassion

Red: Passion, energy, excitement, danger, speed, impulsive action, stimulation, assertiveness, aggression, strength, sex, revolt, war

Silver: Prestige, cold, scientific, stability

Turquoise: Intuitive, insightful, inventive, original, renewal, change

White: Pure, virginal, clean, youthful, mild, peace, truthfulness, enlightenment

Yellow: Warmth, cheer, happiness, vitality, change, progress, clarity, communicativeness, affirmation.

Given the above, red, black, and copper/bronze would seem to head the list of the most sexually attractive colours.

Research shows that colour affects shopping habits. Red-orange, black, and royal blue attracts impulse buyers. Pink, light green, light and navy blue attract tight budget shoppers. Pink, rose, and sky blue attract conformists
