Take a one-minute look at their technique; the steps are written out below.
Before You Start
Plant and Gruenwedel provided their Adobe Stock video clip so you could practice applying this technique yourself. Notice that the color we’re interested in appears in a focused area of the shot rather than in multiple places. The video also shows good contrast and color saturation, making it ideal for this effect. Start a new project in Premiere Pro, import the clip (File > Import), and drag it to the timeline.
Step 1: Apply the Effect
Open the Effects panel (Shift+7), enter change to color in the search field, and drag the Change to Color effect to the clip.
Step 2: Select a Base Color
Open the Effect Controls panel (Shift+5). In the Change to Color section, use the From eyedropper to sample the color you want to replace. The color changes to red by default.
Step 3: Refine the Color Selection
Make slight adjustments to the Tolerance (Hue) settings and Softness to fine-tune your color selection.
Step 4: Pick a New Color
Click the To color chip and choose a new target color. With the playhead at the start of the clip, click the stopwatch next to To. This creates a starting animation keyframe.
Step 5: Animate the Color
Advance the playhead and pick another To color to set a new keyframe. Continue moving the playhead and setting a new color at various intervals to animate the color flow throughout the shot. Press the spacebar to preview the final effect.
Create a Moving Spectrum
Match coloration changes to a beat to add dynamic style to your videos.
