Chroma is a mobile application that enables users to explore their mood spectrum through color shades and simple graphics. The app is based on evidence-based cognitive behavioral therapy (CBT) journaling techniques, which encourage users to practice self-reflection through writing and colors. By selecting various gradients, solid colors, or images, users can discover their unique mood shades and gain a deeper understanding of themselves. Additionally, it includes an image creation system to help them visually manifest their viewpoints.
