Complementary Colours in Web Design: Enhancing Visual Impact and Readability
Complementary colours are pairs of colours that, when combined, cancel each other out to produce a grayscale colour like white or black.
They sit opposite each other on the colour wheel, with common pairs including red and green, blue and orange, and yellow and purple. Understanding and utilising complementary colours is vital for creating vibrant, dynamic, and visually appealing websites in web design. When used correctly, these colours can enhance a design's visual impact, improve readability, and create a clear hierarchy of information.
The strategic use of complementary colours can draw attention to key elements, such as CTAs and important content, by providing a high contrast level. This makes the elements stand out and improves the user's focus and direction. However, using complementary colours judiciously is essential; overuse or poor combinations can lead to visual tension and discomfort, detracting from the user experience.
"Complementary colours, when used effectively, can bring a design to life with vibrant contrast and clear focal points. They are a powerful tool for directing user attention and enhancing the overall aesthetic of a website."
- Elwyn Davies, Pixelhaze Academy.
