Unity 3D's Gradient is a handy data type but comes with some limitations: for example you cannot set more than 8 color keys in its editor and RGB is the only color space available. ColorBand data type offers an alternative with less limitations. Creating ColorBands is fun and easy; they are stored as assets and can be accessed from code through an Evaluate method to get the color at time t, as for Gradient. RGB (or HSV) values are described by individual curves, allowing a better control over how the color function evolves between your points. Color bands are used in all kinds of applications including games, data visualization and other fields.
