Colours sized proportionally, relative to how much they’re useful in Greenpeace collateral.
Green is Greenpeace’s main colour — The Greenpeace green (#66cc00) is most commonly used in the logo and features prominently as an emphasis colour in both our print and digital communications. It is not essential that you use this colour in all of your communications, but be aware that the logo should only ever appear in this green, black or white.
Dark green, white, light grey, and dark grey are secondary, neutral colours. They are good for backgrounds, and balancing out the brighter, more intense colours.
Red is our main accent colour. Use it for buttons, highlights, and calling attention to the most important parts of your design.
Aqua, blue and yellow are secondary accent colours. When you’re already using all the other colours, a high-contrast colour from this list can provide variety and give you more alternatives to work with.
Designing for sufficient colour contrast
The next thing to crack is ensuring that the foreground (text) and background colours you use provide enough contrast to allow colour-blind users or those using a monochrome screen to view information. This is equally important when designing for text over the top of an image or video sequence. As a general rule, lighter colours like white and yellow should only be used on very dark backgrounds and darker colours like black and blue should only be used on light or white backgrounds.
