This book is primarily a picture book. Many pictures are available on Wikimedia Commons for use here. Please look on that website for suitable images before uploading new images to Wikibooks.
Where possible, try to follow the formatting of existing pages when creating new pages. Wikijunior:Colors/Blue is a pilot page that can be copied for formatting. Try to format the text to be large and colored appropriately. On the "White" page, do not make the text white, because it will be too hard to read.
