A book cover must immediately draw readers in if you hope to peak their interest and ultimately get the sale. It is a critical component of your author branding and needs to not only fit the genre that you're writing in, but also portray the tone and overall message or theme of your book. The colors, fonts, and images you choose must work together and be clear to the reader. In this collection of interviews, authors, designers, and publishers share tips and best practices for designing an effective book cover that will instantly grab the attention of readers.
Really interesting advice. I wasn't aware how certain colors could make or break your cover design. I like to keep my covers simple. I don't like a lot of distractions. I feel that warm & dark backgrounds with a single picture forces the imagination to wonder. Curiosity is how I try to grab my readers. If you see a book with a single title & a warm background, I would think a person would be more curious about it than one with a long title & many bright colors. Now, it may be a bit different with established authors, but I'm sure they maintain a certain model.
Great starting point
