色彩分离节点

色彩分离 是指在图像的高光和阴影部分应用不同的色调。这种技术在摄影和调色中被广泛应用，通过为明亮和黑暗区域赋予不同的色调，从而营造氛围、增强对比度或赋予图像独特的风格。

For example, warm highlights and cool shadows can evoke a cinematic or nostalgic look, while complementary tones can create stylized or dramatic effects.

Shifts the midpoint that defines what parts of the image are considered highlights or shadows. Increasing this value favors the highlight color; decreasing it favors the shadow color.
