You are using Exclaimer Cloud, and you want to know more about how Dark mode can affect email signatures?
Dark mode is an accessibility setting that changes the colour scheme of an interface, minimizing the amount of blue light to enhance readability and reduce eye strain. This is great for anyone who is light sensitive and working late hours.
To check if dark mode settings in HTML have been set for background colour and font colours, use:
If a colour is set (for example, black), the setting will reverse the colours; black will change to white and white will change to black.
Unfortunately, we cannot override the dark mode settings ourselves, but there are recommended steps you can take to ensure the signature works correctly.
- Avoid background colours where possible; white can become black, and black can become white, as though they are inverted. Anything off white can become grey.
- Use images with a transparent background to allow the background to show through the image.
- If text is used as an image, it is recommended to add a white stroke to the text within the image before adding it to the template.
- Rendering the signature as a bitmap image can help resolve the issue if you use a background colour, such as black. This will embed the colours used in the signature, resulting in the signature staying the same at all times.
However, this can cause the signature to become an attachment or strip out of forward and reply emails. Hyperlinks may not work if you like to see the signature when composing an email. For more information, see Hyperlinks are missing from my signature.
