If you are considering changing the branding of your company, you need to carefully consider how you are going to do this. It may be that you want to change you log and / or company name and therefor your colour ways may also change. Look at a rebranding as a positive move, allowing you to consider new developments that have happened since your brand was first established, and how you can incorporate them in to your new branding.
When changing a logo or company name, be sure to change this everywhere such as on your website, stationery, social media accounts and sign written vehicles etc. You need to consider the changes you make on your website to ensure that you do not miss anything and that your customers are not confused by the changes. The changing of a logo may mean you also need to change the colours of the website, it may be worth while keeping the layout the same for a while until customers have become familiar with your new branding. This will give them confidence that you are still the same business just with a new logo. Also ensure that you make the changes throughout the site including downloadable PDF’s etc. which are often missed.
