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. Pink is the sweet side of red. It's cotton candy and bubble gum and babies.
