Pink

Cotton Candy and Little Girls:
Pink is a softer, less violent red. Pink is the sweet side of red. It's cotton candy and bubble gum and babies, especially little girls.
Nature of Pink:
While red stirs up passion and action, studies have shown that large amounts of pink can create physical weakness in people. Perhaps there is a tie-in between this physical reaction and the color's association with the so-called weaker sex.
Culture of Pink:
In some cultures, such as the US, pink is the color of little girls. It represents sugar and spice and everything nice. Pink for men goes in and out of style. Most people still think of pink as a feminine, delicate color.
Using Pink:
Both red and pink denote love but while red is hot passion, pink is romantic and charming. Use pink to convey playfulness (hot pink flamingoes) and tenderness (pastel pinks). Multiple shades of pink and light purple or other pastels used together maintain the soft, delicate, and playful nature of pink. Add strength with darker shades of pinks and purple and burgundy.
Using Pink with Other Colors:
All shades of pink get sophisticated when combined with black or gray or medium to darker shades of blue. Medium to dark green with pink is also a sharp-looking combo.
