As you can imagine, colour plays a key role in just about everything we do, and accurate and high-quality colour reproduction is something in which we take great pride. With this in mind here’s a helpful basic guide to colour modes, choosing colour palettes and the meaning colours convey.
When printing we primarily use 4 colours, cyan, magenta, yellow and black (CMYK) to reproduce colour images. These 4 colours can be overlaid to produce a range of different colours. On other occasions, especially when printing business stationery, for instance, we can use spot colours and we usually use the Pantone system for this. This system uses a selection of pre-mixed inks to create the desired colours.
CMYK RGB Pantone
On screen, images are displayed as RGB (red-green-blue), and when printed will be made up of CMYK (cyan-magenta-yellow-black). Moving from one of these colour modes to another can cause variations in colour from what is viewed on-screen to the printed product. RGB has a much wider range, therefore, giving more depth, making images look brighter and more colourful compared to the printed product. What’s more, because all screens are different, with variations in brightness and contrast settings, an image may look different, even from one screen to the next. We use colour profiles in our design applications to simulate the final printed colours so that what we see on screen is as close to what can be produced on our presses as we can make it.
This graph shows a representation of the different colour spectrums achievable with each colour mode. As you can see CMYK has a much smaller colour gamut than RGB.
Colours have widely accepted meanings and associations, although significantly these vary from culture to culture. Each colour can have positive and negative connotations:
Yellow | + bright, energy, sun, creativity, intellect, happy | – irresponsible, unstable
Orange | + bright, energy, sun, creativity, intellect, happy | – arrogance, insincerity
Red | + love, energy, power, strength, passion, heat | – anger, danger, warning
Pink | + healthy, happy, feminine, compassion, sweet, playful | – weak, immaturity
Purple | + royalty, nobility, spirituality, luxury, ambition | – mystery, moodiness
Blue | + tranquillity, love, loyalty, security, trust, intelligence | – coldness, fear
Turquoise | + spiritual, healing, protection, sophisticated | – envy
Green | + money, growth, fertility, freshness, healing | – envy jealousy, guilt
Beige | + dependable, flexible, crisp, conservative | – dull, boring, conservative
Brown | + friendly, earth, outdoors, longevity, conservative | – dogmatic, conservative
Grey | + security, reliability, intelligence, solid | – gloomy, sad, conservative
Black | + protection, dramatic, classy, formality | – death, evil, mystery
Silver | + glamorous, high tech, graceful, sleek | – dreamer, insincere
Gold | + wealth, prosperity, valuable, traditional | – greed, dreamer
Once you’ve chosen a primary colour that best suits your purpose, you can select a palette of colour. Here are a few tried and tested methods to help decide on an ideal colour palette:
Monochrome A scheme derived from a single base hue using tints, shades and tones. If a colour is made lighter by adding white, the result is called a tint. If black is added, the darker version is called a shade. If grey is added, the result is a different tone.
Complementary Colours that are opposite each other on the colour wheel are considered to be complementary colours. Complementary colours are tricky to use in large doses, but work well when you want something to stand out.
Split complementary Is a variation of the complementary colour scheme. From the base colour, it uses the two colours adjacent to its complement. This has the same strong visual contrast as the complementary colour scheme but creates less tension.
Double complementary This scheme uses four colours arranged into two complementary pairs. This rich colour scheme offers plenty of possibilities for variation. It works best if you allow one colour to be dominant.
Analogous Uses colours that are next to each other on the colour wheel. They usually match well and create a comfortable design. Make sure you have enough contrast when choosing an analogous colour scheme.
Triad A triadic colour scheme uses colours that are evenly spaced around the colour wheel. Triadic colour harmonies tend to be quite vibrant, even if you use pale or unsaturated versions of your hues.
For an example of a colour palette designed to support a brand take a look at the work we did for the relaunched Sudanese Programme branding.
