Design a logo or a mascot for Hawaii. The mascot could be a Hawaiian green sea turtle, one of Hawaii's most iconic creatures. The turtle could be presented in a friendly, cartoonish style with a lei (Hawaiian flower garland) around its neck. For the logo, incorporate symbols of Hawaiian culture such as palm trees, surfboards and the state's unique typography. The primary colours should be a mix of vibrant blues, greens, and yellows to reflect the region's natural beauty. The elements should be arranged harmoniously, representing the spirit of aloha - welcoming, friendly, and embracing.
