Chromium CSS Color Interpolation and Resolution Analysis

These sources detail CSSColorInterpolationType::ResolveInterpolableColor, a critical "late-binding" function within Chromium’s Blink animation engine. This function serves as a bridge that converts abstract, animated color representations into concrete blink::Color values at the moment they are applied to a style. It specifically manages runtime-dependent variables that cannot be resolved early, such as currentColor, visited versus unvisited link states, and various color-scheme preferences. Rather than performing the mathematical interpolation itself, the helper delegates that logic to underlying polymorphic classes like InterpolableColor and InterpolableStyleColor. This architecture allows the browser to support complex CSS Color Level 4 and 5 features, including deferred color functions and relative color syntaxes, while maintaining strict privacy for visited links. Ultimately, the system ensures that animations remain visually accurate even when an element's dynamic context, such as its inherited text color, changes during the animation's progress.
