Why Colour Matters

Filed under Articles

Although colour is a “soft science,” substantial research shows why colour matters and how it plays a pivotal role in all our visual experiences.

Colour and Marketing

1. Research conducted by the secretariat of the Seoul International Colour Expo 2004 documented the following relationships between colour and marketing:

92.6 percent said that they put most importance on visual factors when purchasing products. Only 5.6 percent said that the physical feel via the sense of touch was most important. Hearing and smell each drew 0.9 percent.

When asked to approximate the importance of colour when buying products, 84.7 percent of the total respondents think that colour accounts for more than half among the various factors important for choosing products.

2. Research reveals people make a subconscious judgment about a person, environment, or product within 90 seconds of initial viewing and that between 62% and 90% of that assessment is based on colour alone.

3. Research suggests 73% of purchasing decisions are now made in-store. Consequently, catching the shopper’s eye and conveying information effectively are critical to successful sales.

Color and Brand Identity

1. Colour increases brand recognition by up to 80 percent

2. Heinz
Colour influences brand identity in a variety of ways. Consider the phenomenal success Heinz EZ Squirt Blastin’ Green ketchup has had in the marketplace. More than 10 million bottles were sold in the first seven months following its introduction, with Heinz factories working 24 hours a day, seven days a week to keep up with demand. The result: $23 million in sales attributable to Heinz green ketchup [the highest sales increase in the brand’s history]. All because of a simple colour change.

3. Apple Computer
Apple brought colour into a marketplace where colour had not been seen before. By introducing the colourful iMacs, Apple was the first to say, “It doesn’t have to be beige”. The iMacs reinvigorated a brand that had suffered $1.8 billion of losses in two years. (And now we have the colourful iPods.)

Colour Increases Memory

If a picture is worth a thousand words, a picture with natural colours may be worth a million, memory-wise. Psychologists have documented that “living colour” does more than appeal to the senses. It also boosts memory for scenes in the natural world.

By hanging an extra “tag” of data on visual scenes, colour helps us to process and store images more efficiently than colourless (black and white) scenes, and as a result to remember them better, too.

Colour Engages and Increases Participation

Ads in colour are read up to 42% more often than the same ads in black and white (as shown in study on phone directory ads).

Colour Informs

Colour can improve readership by 40 percent (1), learning from 55 to 78 percent (2), and comprehension by 73 percent (3).

Colour Attracts Attention

Tests indicate that a black and white image may sustain interest for less than two-thirds a second, whereas a colored image may hold the attention for two seconds or more. (A product has one-twentieth of a second to halt the customer’s attention on a shelf or display.)

People cannot process every object within view at one time. Therefore, colour can be used as a tool to emphasize or de-emphasize areas.

A Midwestern insurance company used colour to highlight key information on their invoices. As a result, they began receiving customer payments an average of 14 days earlier.

Other Research

92% Believe colour presents an image of impressive quality
90% Feel colour can assist in attracting new customers
90% Believe customers remember presentations and documents better when colour is used
83% Believe colour makes them appear more successful
81% Think colour gives them a competitive edge
76% Believe that the use of colour makes their business appear larger to clients

Colour and the Senses

General facts about sensory input and human beings:

Although the olfactory sense was a human being’s most important source of input in the pre-historic era, sight became our most important means of survival. Furthermore, as hunters and gatherers in the early days of our evolution, we experienced a variety of colours and forms in the landscape. This has become part of our genetic code.

In our current state of evolution, vision is the primary source for all our experiences. (Current marketing research has reported that approximately 80% of what we assimilate through the senses, is visual.)

Our nervous system requires input and stimulation. (Consider the effects of solitary confinement in jails.) With respect to visual input, we become bored in the absence of a variety of colours and shapes. Consequently, colour addresses one of our basic neurological needs for stimulation.

Color and Visual Experiences

“It is probably the expressive qualities (primarily of colour but also of shape) that spontaneously affect the passively receiving mind, whereas the tectonic structure of pattern (characteristic of shape, but found also in colour) engages the actively organizing mind.”

Colour In The Eye

Filed under Articles

The ability of the human eye to distinguish colours is based upon the varying sensitivity of different cells in the retina to light of different wavelengths. The retina contains three types of colour receptor cells, or cones. One type, relatively distinct from the other two, is most responsive to light that we perceive as violet, with wavelengths around 420 nm. (Cones of this type are sometimes called short-wavelength cones, S cones, or, misleadingly, blue cones.) The other two types are closely related genetically and chemically. One of them (sometimes called long-wavelength cones, L cones, or, misleadingly, red cones) is most sensitive to light we perceive as yellowish-green, with wavelengths around 564 nm; the other type (sometimes called middle-wavelength cones, M cones, or, misleadingly, green cones) is most sensitive to light perceived as green, with wavelengths around 534 nm.

Light, no matter how complex its composition of wavelengths, is reduced to three colour components by the eye. For each location in the visual field, the three types of cones yield three signals based on the extent to which each is stimulated. These values are sometimes called tristimulus values.

The response curve is a function of wavelength for each type of cone. Because the curves overlap, some tristimulus values do not occur for any incoming light combination. For example, it is not possible to stimulate only the mid-wavelength/”green” cones; the other cones will inevitably be stimulated to some degree at the same time. The set of all possible tristimulus values determines the human colour space. It has been estimated that humans can distinguish roughly 10 million different colours.

The other type of light-sensitive cell in the eye, the rod, has a different response curve. In normal situations, when light is bright enough to strongly stimulate the cones, rods play virtually no role in vision at all. On the other hand, in dim light, the cones are understimulated leaving only the signal from the rods, resulting in a colourless response. (Furthermore, the rods are barely sensitive to light in the “red” range.) In certain conditions of intermediate illumination, the rod response and a weak cone response can together result in colour discriminations not accounted for by cone responses alone.
