根据两个颜色根据比例求过渡色

The issue provides a Java getPaintColor method but names no repository file, entry point, test, or expected change. First inspect the blog's source to determine where this color calculation belongs and clarify the intended behavior; done should include an agreed location and a way to verify the interpolated color result.
