FeralUI Gradient Builder — gradient generator
A free gradient editor with traditional Japanese colour palettes, shape and grain controls, and export options for images, video and code.

ColorFlow creates multicolour mesh gradients for digital graphics. Instead of one linear transition, it offers a colour grid with adjustable control points. Presets provide starting points for backgrounds, covers and visual experiments. The editor offers rectangular and circular topology, grid sizes and different canvas aspect ratios. Points and handles shape the transitions. RGB, OKLab and LCH are available for colour interpolation. The creator describes effects including grain, blur, chromatic aberration and glass distortion. Colour correction provides further ways to change the result. Effects can be combined, though text legibility over a finished background still needs its own check. ColorFlow also offers gradient motion, cursor interaction and webpage embedding. Its official editor code includes PNG, JPG, WebP and MP4 export options, plus saving and loading .colorflow files. Rendering availability depends on the browser and graphics environment. The creator explicitly permits free use for personal projects, client work and commercial products. This is not a separate licence to redistribute the application’s source code. A compatible browser graphics environment is required; check rendering and your intended export format on your device before starting a large project.
