How do you adjust the hue, saturation, and brightness of your rotoscope layers?

1 Choose a color mode

Before you start adjusting the colors of your rotoscope layers, you need to choose a color mode that suits your project. After Effects offers three color modes: RGB, HSL, and HLS. RGB stands for red, green, and blue, and it is the most common color mode for digital images. HSL stands for hue, saturation, and lightness, and it is useful for changing the color tone and intensity of your rotoscope layers. HLS stands for hue, lightness, and saturation, and it is similar to HSL but with a different order of parameters. You can switch between color modes by clicking on the color wheel icon next to the color picker in the Effect Controls panel.

2 Apply color effects

After you choose a color mode, you can apply color effects to your rotoscope layers to adjust the hue, saturation, and brightness. After Effects has several color effects that you can find under the Color Correction category in the Effects & Presets panel. Some of the most useful ones for rotoscoping are Hue/Saturation, Levels, Curves, and Color Balance. Hue/Saturation lets you change the hue, saturation, and lightness of your rotoscope layers individually or globally. Levels lets you adjust the brightness and contrast of your rotoscope layers by modifying the input and output levels. Curves lets you adjust the brightness and contrast of your rotoscope layers by creating curves for each color channel. Color Balance lets you adjust the amount of red, green, and blue in your rotoscope layers.

3 Use adjustment layers

One of the best ways to adjust the colors of your rotoscope layers is to use adjustment layers. Adjustment layers are special layers that apply effects to all the layers below them in the timeline. You can create an adjustment layer by clicking on the New Layer icon at the bottom of the timeline and choosing Adjustment Layer. Then, you can apply any color effect to the adjustment layer and adjust its opacity and blending mode to fine-tune the result. You can also use masks and track mattes to limit the effect of the adjustment layer to specific areas of your rotoscope layers.

4 Use color pickers and eyedroppers

Another way to adjust the colors of your rotoscope layers is to use color pickers and eyedroppers. Color pickers are tools that let you choose a color from a color wheel or a color palette. Eyedroppers are tools that let you sample a color from an image or a layer. You can use color pickers and eyedroppers to match the colors between your rotoscope layers and the original footage or to create a harmonious color scheme. You can access color pickers and eyedroppers by clicking on the color swatches in the Effect Controls panel or by using the keyboard shortcuts.

6 Preview and render

The last thing you need to do is to preview and render your rotoscope layers with the adjusted colors. You can preview your rotoscope layers by pressing the spacebar or by using the preview panel. You can also toggle the effects on and off by clicking on the fx icon next to the layer name in the timeline. To render your rotoscope layers, you need to add them to the render queue by choosing Composition > Add to Render Queue or by pressing Ctrl+M. Then, you can choose the output format, codec, resolution, and quality of your render and click on the Render button.
