互补色平衡Complementary Color Balance
学习目标LEARNING OBJECTIVES
学完你能用互补色（Complementary Colors）原理判断"画面偏什么色、该加什么色"，并说清为什么加互补色能中和偏色。
概念说明CONCEPTS
互补色是色轮上正对位置的两种颜色，把互补色加进画面就能中和对应的偏色——这是白平衡和一切去偏色操作的底层原理，色轮、曲线、Offset 全在吃这一套。
- 三组经典对冲：蓝 ↔ 黄、红 ↔ 青、绿 ↔ 品红——记住这三对，绝大多数偏色都能对号入座。
- 相加即中和：画面偏蓝就加黄，两种颜色在信号层面互相抵消，画面回到中性。
- 动作永远很小：色轮指示点离中心几像素就够；拖过头等于亲手制造一个反向偏色。
- 灰部是参照物：找画面里本该中性的物体（白墙、灰路、衬衫），它偏什么色，整个画面就偏什么色。
蓝 ↔ 黄 · 红 ↔ 青 · 绿 ↔ 品红。画面偏什么色，就往色轮正对面轻拖。
操作步骤STEPS
- 在调色页面选中一段明显偏色的片段，打开
Scopes切到 Parade
- 看 Parade 三通道哪一路整体偏高——它就是主导偏色
- 在 Offset 色轮上，把中心指示点朝主导偏色的正对方向轻拖几像素
- 拖到 Parade 三通道趋于对齐、灰部回到中性即停
练习PRACTICE
- 找三段分别偏蓝、偏黄、偏绿的素材，先口头说出该加什么色，再用 Offset 色轮验证。
- 故意把指示点拖过头制造反向偏色，再拖回来——体会"几像素就够"的量级。
常见问题FAQ
怎么判断画面到底偏什么色？
盯本该中性的物体——白墙、灰路面、白衬衫。拿不准就开 Parade：哪个通道整体偏高，画面就偏哪个色。
互补色要去哪里查表吗？
不用。色轮上正对面就是：偏蓝向黄拖、偏红向青拖、偏绿向品红拖。具体操作流程见 互补色校正。
加互补色会让画面变灰、变脏吗？
小幅中和不会；拖过头把饱和度对冲没了才会浑浊。动作小、盯灰部，就安全。

After this card you can use the complementary color principle to name "what color the image leans to and what to add", and explain why adding the opposite color neutralizes a cast.
Concepts概念说明
Complementary colors sit opposite each other on the color wheel, and adding one of them to the image neutralizes the cast of the other — this is the underlying principle behind white balance and every de-cast move, whether you use wheels, curves or Offset.
- Three classic pairs: blue ↔ yellow, red ↔ cyan, green ↔ magenta — memorize these three and most casts have an obvious answer.
- Add to neutralize: a blue-tinted shot gets yellow; the two colors cancel each other at the signal level and the image returns to neutral.
- Moves stay tiny: a few pixels off the wheel's center is enough; drag too far and you've manufactured the opposite cast yourself.
- Gray is your reference: find something that should be neutral (a white wall, gray road, a shirt) — whatever tint it shows is what the whole shot leans to.
Blue ↔ yellow · Red ↔ cyan · Green ↔ magenta. Whatever tint you see, nudge toward the exact opposite on the wheel.
Steps操作步骤
- On the Color page, select a visibly tinted clip, open
Scopesand switch to Parade - See which of the three Parade channels rides high overall — that's the dominant cast
- On the Offset wheel, nudge the center indicator a few pixels toward the color opposite that cast
- Stop when the three Parade channels line up and the grays look neutral again
Practice练习
- Find three clips tinted blue, yellow and green respectively; say out loud which color to add before touching the Offset wheel, then verify.
- Deliberately drag the indicator too far to create the reverse cast, then pull back — feel how small "a few pixels" really is.
FAQ常见问题
How do I tell what color the image leans to?
Watch the objects that should be neutral — white walls, gray pavement, a white shirt. Unsure? Open Parade: whichever channel rides high overall is the tint.
Do I need a chart to look up complementary colors?
No. The opposite side of the wheel is the answer: blue cast toward yellow, red toward cyan, green toward magenta. For the full working procedure see Complementary Color Correction.
Will adding a complementary color make the image gray or muddy?
Not with small moves; only over-dragging cancels out saturation and turns things murky. Small moves, eyes on the grays — you're safe.
