One Dad, Two Dads, Brown Dad, Blue Dads

One Dad, Two Dads, Brown Dad, Blue Dads is a children's book by Johnny Valentine and Melody Sarecky. It is designed for 4–8-year-olds, and discusses all kinds of different fathers, including having two dads. In the book a different colored dad, a traditional family, and a family with two dads' children compare dads to find out in the end that they are not that different after all.

The book was one of the three at the center of the 1997 Surrey book-banning controversy, alongside Lesléa Newman's Belinda's Bouquet and Rosamund Elwin and Michele Paulse's Asha's Mums.

Its title is a play on the title of an older Dr. Seuss children's book, One Fish Two Fish Red Fish Blue Fish.

The book was met with challenges primarily for its inclusion of homosexual parents. One such example was when the book was brought into question in the Canadian school system in which James Chamberlain and four fellow litigants spent $400,000 of their own cash to challenge the banning of the book. When brought forward to the Supreme Court of Canada, the following was stated, "no age is too tender for children to learn the value of tolerance". The resulting challenge has allowed free access to the book as the morals taught are that of tolerance regardless of how different one is from another.
