Color Matching B-Roll So It Blends With A-Roll

Why mismatched color shows

When b-roll comes from a different camera or a stock library, its white balance, contrast, and saturation rarely line up with the footage around it. The cut looks wrong even when the shot is great.

The fix is to grade the b-roll toward the main footage, not the other way around. Your primary camera sets the look.

Reading the shot before you grade

• Check white balance first, then contrast, then saturation.
• Use scopes rather than trusting your eye on a bright screen.
• Compare skin tones, since faces reveal mismatches fastest.
• Note the black level, because lifted blacks look washed out next to deep ones.

Match the shadows and the faces. Get those two right and the rest fights less.

Small moves beat big ones

A slight contrast curve and a small white balance nudge usually do more than a heavy grade. Aggressive corrections create noise and banding.

Grade with the whole sequence playing. A shot that looks right on pause can flicker or pop when it moves.

Key takeaways

• Grade b-roll toward your main camera, not the reverse.
• Fix white balance, then contrast, then saturation.
• Trust scopes over your eye for color decisions.
• Keep corrections small to avoid noise.

A color match is invisible when it works. You only see it when it fails.
