You can then select the color that you want your Designer Cover text to be:
Please note that the colors available depend on the fabric you have selected. Some colors are unavailable for certain fabrics. Our Design and Production teams have tried and tested all potential cover text colors on all our fabrics to identify which colors provide the best result for each fabric. This is why not all colors are available for every fabric. We are unable to accommodate requests for custom color and fabric combinations; you will need to select from one of the available options.
Presentation Box Text
You can now add text or designer layouts to your Premium Presentation Box. If you select a Presentation Box layout that includes text, the text on the Presentation Box will revert to the default color option for the fabric. If you would like the text to match your Photo Book or Photo Album cover text color, you will need to manually change the box color.

If your project does not have cover or spine text, you can see how to add it here.
