One-Click Image Recoloring API v2 AI Prompts & Use Cases
After connecting this MCP tool to your AI assistant, you can ask the questions below. Replace bracketed placeholders with your own inputs and use the supported values in Arguments.
New to Nexscope MCP? Follow the connection guide, then use the prompts below. The Integration and Parameters & Response tabs contain the connection steps, call example, and technical reference.
1. Recolor A Product With Chosen Colors
Prompt: Recolor the [specified subject] in [product image] using [one to 25 colors expressed as full HEX, RGB or HSB values]. Use explicit colors without reference-color images.
2. Match Colors From Reference Images
Prompt: Recolor the [specified subject] in [product image] to match [one to 25 color-reference images]. Use image references without an explicit color list.
3. Compare Palette And Reference-Image Recoloring
Prompt: Recolor [the same subject] in [product image] twice: use [one explicit full HEX, RGB or HSB color] in the first request, and [one color-reference image] in the second. Keep the two color-input modes separate. Compare completed results visually for color appearance and retained product detail; do not promise exact physical color matching or a numerical color-error score.
What You Need to Provide
Provide assets you may use and that meet this tool’s documented file, dimension and count limits.
A pending task is not a completed image, video or text result. Retrieve the existing task rather than submitting a duplicate.
