Dark tint on book cover (preview image and proof copy)
From the Lulu knowledgebase I can see this is a common problem - but I haven’t found how to resolve the issue. (see screenshot below),
Please could someone give me some guidance how to fix the issue.
(I know Google+ has an auto-enhance setting which darkens images, Does Lulu have a similar feature?)
Interestingly, the cover is the right colour when I download the PDF file from my Lulu project.
