One important consideration when using foil edge gilding is the colour of the foil. Foil comes in a wide variety of colors, allowing you to customise your design to match your brand or project's colour scheme. Some popular foil colors include gold, silver, rose gold, copper, black and holographic silver/gold, but the possibilities are virtually endless.

When choosing a foil colour for your edge gilding, it's important to consider the overall look and feel you're trying to achieve. Gold and silver are classic choices that exude luxury and sophistication, while copper adds warmth and a vintage feel. Black is a versatile options that can work with a range of designs, and bold colors like holographic silver/gold can add a range of colours depending upon the light and create a dramatic effect. It's also important to consider how the foil colour will complement the rest of your design. If you have a predominantly warm colour palette, a warm-toned foil like gold or copper may work best, while a cooler-toned design may benefit from a silver or blue foil.

Another factor to consider when choosing a foil colour for your edge gilding is the availability of the colour. Not all coloured are created equal in terms of their suitability for foil edge gilding. Some colours may be more difficult to source or may come at a higher cost, so it's important to work with a printer or bookbinder who has experience with foil edge gilding and can help you choose the best option for your project. Ultimately, the colour of the foil you choose for your edge gilding can have a significant impact on the overall look and feel of your printed materials, so it's worth taking the time to carefully consider your options.
