I'm 'self-publishing' a book for my family & friends. I want the book to stand out on the shelf my question is

[Mike O]

what colors would have the greatest conrast on the spine of a book, so if you're looking at books on a shelf you would have to look because of the colors?

I am dying, this book will be given out at my memorial service. It's my version of all the great memories with these poeple that made my life so very enjoyable.
Someone questioned if my dying may be by choice... no, I have stage 4 metastatic breast cancer with 'mets' to my liver, brain and spine... Not my choice, my destiny...
