Can AI video tools generate a selective color effect where only the product stays in color and everything else is black and white?

Yes — the invideo agent can render an entire scene in black and white while keeping only the hero product in full color, in a single video generation pass. You prompt it directly as a selective-color shot, lock the look on a still keyframe first, then animate that locked frame so the isolation holds across the clip.

Treat selective color as a directorial instruction on the keyframe, not a post effect. invideo is an agentic video tool that routes shots to the right image and video models (GPT-Image-2, Nano Banana, Recraft for stills; Seedance 2.0, Veo, Kling for motion) — so you can lock the look as a still, then animate it without leaving one chat.

Write the selective-color brief into the keyframe prompt. Be explicit about what stays colored and what desaturates: "entire scene rendered in black and white, only the [product] in full saturated color, everything else — skin, wardrobe, background, props — pure monochrome." Generate the still first. This is the image-first iteration discipline — cheap to redo, and you only spend video credits on a locked frame. In a documented jewelry production, the team built the base image with GPT-Image-2 for aesthetic, then ran Nano Banana to lock the exact product into it; the same dual-model pass works here to keep product detail crisp while the rest of the frame goes mono.

Raise product–background contrast before you generate. Automated subject isolation (whether the model does it natively or you fix it in post) is cleanest when the product color is far from anything else in the frame: a red bottle on a grey street, a gold watch on a charcoal desk. Neutral, low-saturation backgrounds and a single hard key light separating the product from its surroundings give the model an unambiguous subject to keep colored.

Validate on three focal distances before committing. Generate the locked selective-color frame as a close, a mid, and a wide — confirm the isolation holds at each scale before you batch video. This is the same three-distance product-consistency check used for jewelry and intricate products; for selective color it surfaces the typical failure (color bleeding onto a hand, a reflection, or a label) while you can still fix the prompt cheaply.

Animate the locked frame in Seedance 2.0. Use the still as the reference (image-to-video) and instruct the motion clearly — camera move, product action, beat — while restating the color rule in the video prompt: "maintain selective color: only the product in color, everything else black and white, no color creep onto skin, hands, or environment." Restating the rule on the motion pass is what keeps the isolation stable across frames.

If the isolation drifts mid-clip, fall back to a post pass. Pull the clip into your editor and apply a selective desaturation (mask the product, desaturate everything else) or a black-and-white LUT with a hold-out on the product hue. invideo's Slate timeline handles the stitch and basic grade in-platform; for tighter masks, a hue-based key on the product's signature color is usually enough when contrast is high. Hridaye, invideo's creative director, frames the general principle this way: "The point of working with AI is to take whatever is in your head and make it more tangible and then I iterate. So you start fairly broad." Start broad on the selective-color brief, tighten the contrast and the keyframe, then animate.

Watch some of these to see what works for you:
