### Remarks

This mode finds the two keys adjacent to the requested evaluation time, and interpolates between them.

Note that a simple linear interpolation between color keys of very different hue can look unnatural. Using [GradientMode.PerceptualBlend](/engine/6000.5/script-reference/unityengine/gradientmode/perceptualblend.md) can often result in a more natural looking color blend.
