Still on the colorful subject of brand-building and the inseparable role of color, I found an excellent reference source, via Martin Lindstrom, Brand Strategist, and his books “Buyology” and “Brand Sense”.
… Color is essential to the brand-buiding process because it’s the most
visible first point of communication.
… School buses, police cars, and garbage trucks are first and foremost distinguished by their color. Think mail vans, and the immediate thought is of their color.
… Using a color in a logo, and then sporadically splashing it across print materials will not automatically build or maintain the color ownership. However, colors create clear
associations, and it’s these associations that will benefit your brand.
