When choosing colors for your content (from layout design to fonts), think carefully how about these colors will emotionally impact your audience. Colors appeal to the senses. For example, the biggest visual mistake in the restaurant and food industry is grainy, black and white food photography that restaurants use in their menu, websites, and social media. Food photography should pop with rich, appetizing colors. The dishes should LOOK delicious and appealing and not turn your customers' stomachs as soon as they look at the pictures.
Before you go wild with color, consider the psychology behind colors and the feelings they evoke:
Green - a healing color tied to health and also related to animals, nature, balance and harmony. Green can also be tied to money and finance (i.e. money green).
Red - feelings of passion, love, action, strength, power, boldness, sense of adventure etc. and can also be considered an "angry" color (i.e. fire-engine red)
Blue - Soft and harmonious (pale, softer pastel blues) and darker blues reflect professionalism and success.
Purple - Royal, regal and luxurious (deep bold purple) or whimsical, dreamy, wistful (softer lavender shades)
Orange - Fun, creative, youthful, vibrant and energetic
Pink - Sweet, tender, and youthful/innocent
Brown - Earthy and natural
Grey - Reserved and neutral
White - Clean, pure, simple
Black - Serious, formal, mysterious/secretive
If design and color aren't your forte, hire a professional designer to help you choose the best colors, layout design, etc. for your content and site. The wrong color choices could easily scare or turn off your targeted audiences.
