True and the Rainbow Kingdom follows 8-year-old True and her best friend Bartleby the cat, as they help the whimsical citizens of the Rainbow Kingdom, a wondrous, colorful universe filled with delightful and fantastical citizens. True is the only one with the ability to activate the magical powers of the Wishes of the Wishing Tree, solve problems in the Rainbow Kingdom, and empower viewers with her imagination, mindfulness and empathy.
True (voiced by Michela Luci): A strong heroine. True possesses a warm heart, a clever mind and boundless energy. She accepts every challenge head on with a beaming smile. What makes True “truly” extraordinary is that she is the only one in the Rainbow Kingdom who can activate the Wishes’ special powers that unleash magical energy.
Bartleby (voiced by Jamie Watson): A cat and True’s funny sidekick, Bartleby has a lot of bravado and the gift of gab. Only True, his bestie, knows he is actually a bit of a scaredy-cat. He is one opinionated kitty and provides a lot of commentary, which helps trigger True’s creative problem solving skills.
Rainbow King (voiced by Eric Peterson): The lovable ruler of the Rainbow Kingdom, he is a kind, sympathetic and humble king. Though he possesses a wealth of knowledge, he shares his wisdom in riddles adding fun complexity to True’s adventures. He will do anything to help True on her journey but he knows that “true” success is achieved when True solves problems all on her own.
Zee (voiced by Dante Zee): Zee is True’s buddy, an apprentice to the Rainbow King, and the wish keeper. One or two years older than True, Zee is a trained “Wishologist”, which means he takes care of the Wishes and he knows all about their strengths and powers. Once a problem arises in the kingdom, True seeks out Zee’s advice and wish help in the Wishing Tree.
Grizelda (voiced by Anna Bartlam): Grizelda is a self-centered young princess. Deep down she realizes she needs a friend like True. Although True tries to reach out to the Princess, Grizelda’s self-absorbed ways can make that challenging. However, love in Rainbow Kingdom is unconditional, so True never stops trying. Grizelda is just someone who’s a little selfish which only means she needs a little more love!
Frookie: A dog and Grizelda’s sidekick. Looks out for the difficult princess because he knows the inner Grizelda is not so bad.
The Wishes: Non-verbal but highly expressive, the wishes communicate with goofy gestures and sweet sounds. Each one has a unique, big personality that compliments or contrasts their power. The Wishes share a special bond with True but until they are called to action, they stay busy training with Zee. Each Wish is imbued with a special power that only True can “Spark”.
True and the Rainbow Kingdom was originally to be named "Wish Come True".
Developments of the series began as early as 2013, with a planned toy line.
True had a slightly different design, carrying a satchel for the Wishes instead of her standard backpack.
It is one of the first television series to be exclusively rendered on a GPU.
A sneak peek screening of the series was held on August 10, 2017 at a Pacific Theatres venue at The Grove at Farmers Market in Los Angeles. Among the attendees and guests were Frank Falcone, Bill Schultz, Pharrell Williams, the FriendsWithYou duo, Kelly Rowland, Christina Milian, and Tyga.
