Silver and black with gold accents are colors for an elegant 70th birthday, while green, yellow and red are colors for a more laid-back 70th birthday. Rose pink and cream are birthday colors for a woman's 70th birthday, and navy and gold make good birthday colors for a man's party.
Use silver, black and gold as a color scheme for a 70th birthday held at a banquet hall or fancy restaurant as they are elevated colors. Primary colors such as yellow, red and green are ideal for more casual 70th birthdays held in parks and backyards or at sporting events. Choose 70th birthday colors based on the birthday person's preferences.
