To isolate one color in Premiere Pro — keeping it vibrant while everything else goes black and white — use the Hue vs Saturation curve in Lumetri Color. Add three points around the color you want to keep, then drag the outer points down to drain saturation from every other hue. No plugins required.
What this effect does
The single-color look keeps one color visible (red lips, a yellow umbrella, a green shirt) while the rest of the frame turns grayscale — a stylized, cinematic pop perfect for music videos, fashion edits, and product showcases.
How to isolate a color
Open Lumetri Color
Go to Window > Lumetri Color and select your clip in the timeline.
Find Hue vs Saturation
Open the Curves tab and scroll to the Hue vs Saturation graph — this is where you'll isolate the color.
Isolate your color
To keep red, click three points on the curve surrounding the red range, then drag the two outer points all the way down. Everything except the protected hue loses its saturation.
Fine-tune the range
Tighten or widen the points to control how much of the color stays, and drag them in if nearby tones bleed through.
Clean up the edges
Similar tones (skin, a tongue, reflections) can hold onto color you meant to drop. Tighten the curve points, and for stubborn areas add a mask around the part you want to protect. On fast-moving footage, motion blur and quick cuts hide small imperfections.
Pro tip: this works best when the color you're keeping is distinct from skin tones. If your subject's color sits near orange or red, expect to mask faces and hands so they don't keep their color too.
