学习目标LEARNING OBJECTIVES

学完你能看懂 HSL 曲线（HSL Curves）"X vs Y"的命名逻辑，会用 Hue vs Sat 和 Hue vs Hue 精确调整画面中某一种色相。

概念说明CONCEPTS

HSL 曲线（HSL Curves）是按色相、饱和度、亮度选取并调整的曲线工具——它住在曲线面板里，针对画面中某种颜色改它的属性，全程不用手画遮罩。

  • 命名即用法：名字是"选什么 vs 调什么"——Hue vs Sat 选中某色相调它的饱和度，Hue vs Hue 把某色相转成另一色相。
  • 点一下就取样：用取色器在画面目标颜色上点击，曲线自动出现三个点——中间是选中的色相，两侧点限定影响范围。
  • 六种模式一套逻辑：Hue / Sat / Lum 两两组合共六条，入门先掌握 Hue vs Sat 与 Hue vs Hue 两条就够。
  • 专治"画不出形状"：区域边缘复杂、不规则，或就是要按颜色选取——窗口圈不出来时，换曲线。

操作步骤STEPS

  1. 打开曲线面板，点右上角的 Hue vs Sat 按钮
  2. 把取色器移到画面目标颜色上点击，曲线上出现三个控制点取色器在画面中取样色相
  3. 向上拖中间的点增加该色相的饱和度，两侧点控制受影响的范围拖动中间点增加饱和度
  4. 要改变颜色本身，切到 Hue vs Hue，取样后把中间点朝目标色方向轻拖
  5. 想让点只上下移动，拖面板上的 Saturation 参数代替直接拖点

练习PRACTICE

  1. 找一段天空发灰的素材，用 Hue vs Sat 取样天空并提高蓝色饱和度，观察同色系的山、建筑是否被牵连。
  2. 用 Hue vs Hue 把画面里一个小道具换成另一种颜色（如蓝变绿），满意后用 Reset 还原。

常见问题FAQ

为什么点一下画面会出现三个点？

中间点是你在画面里选中的精确色相，外侧两点限定受影响的色相范围。拖动外侧点可以收窄或放宽范围，控制过渡的软硬。

拖点时选中的色相老跑偏怎么办？

直接拖点会同时改动横向位置。想只垂直调整，拖面板下方对应的参数（如 Saturation），水平位置就锁定了。

HSL 曲线和限定器都按颜色选，用哪个？

曲线快、过渡自然，适合"给某种颜色调一调"的轻量活；限定器产出的是精细遮罩，适合要严格隔离的重活（见 限定器）。

Learning Objectives学习目标

After this card you can decode the "X vs Y" naming of HSL Curves and use Hue vs Sat and Hue vs Hue to precisely adjust one hue in the frame.

Concepts概念说明

HSL Curves select and adjust colors by hue, saturation, and luminance — they live in the curves palette and change a color's properties without any hand-drawn mask.

  • The name is the manual: it reads "what's selected vs what's adjusted" — Hue vs Sat picks a hue and changes its saturation, Hue vs Hue turns one hue into another.
  • One click samples: click the target color in the viewer and three points appear on the curve — the middle one is your exact hue, the outer two bound the affected range.
  • Six modes, one logic: Hue / Sat / Lum paired in every combination; mastering Hue vs Sat and Hue vs Hue covers most beginner work.
  • For shapes you can't draw: irregular edges or purely color-based targets — when a window can't outline it, switch to curves.

Steps操作步骤

  1. Open the curves palette and click the Hue vs Sat button in the upper right
  2. Click the target color in the viewer with the eyedropper — three control points appearSampling a hue in the viewer
  3. Drag the middle point up to raise that hue's saturation; the outer points set the affected rangeDragging the middle point to add saturation
  4. To change the color itself, switch to Hue vs Hue, sample again, and nudge the middle point toward the target color
  5. To move a point purely vertically, drag the Saturation parameter in the palette instead of the point

Practice练习

  1. Take a washed-out sky shot, sample the sky with Hue vs Sat, and raise the blue saturation — watch whether same-family colors (hills, buildings) come along.
  2. Use Hue vs Hue to recolor one small prop (blue to green, say), then hit Reset when you're done.

FAQ常见问题

Why do three points appear from one click?

The middle point is the exact hue you clicked; the outer two bound the affected hue range. Drag the outer points to narrow or widen the range and control how soft the transition feels.

My selected hue keeps drifting when I drag a point — why?

Dragging a point directly also moves it sideways. To adjust vertically only, drag the matching parameter (like Saturation) below the graph and the horizontal position stays locked.

HSL Curves or the Qualifier — both select by color, which one?

Curves are fast with smooth transitions, ideal for light "tweak this color" work; the Qualifier produces a precise matte for heavy-duty isolation (see Qualifier).
