Which Blue Is Right? A Reference Map for Video Projects

“Keep the cup blue.”

“Which blue?”

The current product photo showed navy. The latest menu used teal. The public webpage showed a pale blue version. All three were sitting in the same project folder.

The team had also collected a camera sample, a café recording and an old promotional clip. Uploading everything would not settle the disagreement. It would only leave the generation tool to make a decision the team had avoided.

Before writing the prompt, they needed to decide which source controlled each part of the scene.

Give Important Details an Owner

The project is a short concept clip for a seasonal café drink.

A few details need to remain accurate:

• Cup shape
• Product color
• Label position
• Approved product name

The counter, background furniture and small decorative objects are less important. They can change without altering the idea.

A simple reference map separates those two groups:

Source	Controls	Does not control
Current product photo	Cup shape and label position	Product color, claims or camera movement
Current menu	Approved product name	Color or visual style
Brand color decision	Approved product color	Shape or camera movement
Camera sample	Slow push-in	People, location or branding
Café recording	General atmosphere	Dialogue or final music
Public webpage	Current wording check	Product appearance

The camera sample is useful because of its movement. That does not mean the new clip should copy its customers, uniforms, signs or interior.

Writing down that boundary takes less time than explaining it after the wrong details appear in a draft.

Keep the Reference List Short

The reference map can live in a spreadsheet or a small CSV file:

source,controls,priority,owner,status
cup-current.png,cup shape and label position,high,brand manager,ready
menu-current.pdf,product name,high,marketing editor,ready
brand-color-confirmation,product color,high,brand manager,pending
camera-sample.mp4,camera movement,medium,video editor,ready
cafe-room-tone.wav,audio mood,low,producer,rights review
old-promo.mp4,none,excluded,producer,do not upload

The owner column shows who can answer a question. The status column keeps an uncertain source out of the request.

The old promo is excluded because it contains outdated packaging, a licensed song and people who may not be cleared for another use. Removing it is simpler than adding several instructions about what should not be copied.

Stop When Sources Disagree

The product photo, menu and webpage still show different colors. The generation tool should not choose between them.

Record the conflict:

Open issue: approved cup color
Product photo: navy
Menu guide: teal
Public webpage: pale blue
Owner: brand manager
Status: waiting for confirmation

The project can pause until the brand manager confirms the current color. Once confirmed, update the record:

Decision: use teal
Approved by: brand manager
Status: ready

Use the same approach for:

• Product names
• Prices
• Ingredients
• Dates
• Measurements
• Safety instructions
• Performance claims

Do not assume that the newest-looking file is correct. Check it against the approved source.

Upload Only What the Scene Needs

This kind of reference triage is useful when working with Wan 3.0 on JXP, which currently lets users combine a prompt with eligible image, video, audio, document or webpage references.

That does not mean every available file belongs in the same request.

The café scene may need only three:

1. The current product image for the cup shape and label
2. The current menu for the product name
3. The camera sample for movement

The confirmed teal color can be written directly into the prompt. The café recording can remain outside the request if its only purpose is to suggest a quiet room.

Before uploading production material, confirm the current reference rules, available settings, costs and usage terms at the actual access point. These details can change.

Turn the Map Into a Plain Prompt

After the brand manager confirms teal, the brief becomes simple:

Create a short vertical concept clip for a seasonal café drink.

Keep the cup shape and label position consistent with the product image.
Use the confirmed teal color throughout the clip.

Start with the cup on a clean wooden counter. Use a slow push toward it.
A hand places a paper straw beside the cup, and the scene ends with a
brief overhead view.

Use the camera sample for movement only. Do not copy its people,
interior, signs, logos or clothing.

Use soft morning light without changing the cup or drink color.

Sound: low café room noise, a distant espresso machine and the soft
sound of the straw touching the counter. No dialogue, music, prices,
ingredient claims or extra text.

The prompt has one product, one action and one camera path. It does not need to describe every chair, spoon or reflection.

Those extra details would make the instructions longer without making the main idea clearer.

Review Specific Decisions

When the first draft is ready, compare it with the reference map.

Avoid comments such as:

• “The movement feels wrong.”
• “The product is not right.”
• “Something changed.”

Use a note that identifies the moment and the problem:

At seven seconds, the cup changes from teal to pale blue when the view moves overhead.

That tells the next reviewer what happened, where it happened and which decision was not preserved.

If the color is correct but the overhead view arrives too early, record that separately. Changing the image, camera sample, scene order and audio direction at the same time would make the next result harder to understand.

A reference can guide the draft, but it does not guarantee an exact match. Check the complete clip for changes in product shape, color, label position, camera movement, sound timing and background details.

Keep Four Risks Outside the Prompt

Some decisions cannot be solved through better wording.

Before using a reference, check:

1. Rights Confirm that the relevant agreements allow external AI processing, derivative use and the planned publication or promotional reuse. Permission to publish the original material may not cover all three.

2. Sensitive material Do not upload confidential client files, unnecessary personal data, unlicensed music or recognizable voices without suitable authorization.

3. Factual claims A generated café scene cannot verify ingredients, price, nutritional value, product size, taste or real-world appearance. Use approved sources outside the video.

4. Publication context If viewers could mistake the clip for footage of a real café, launch or customer interaction, make its illustrative nature clear.

These checks belong at the start of the project. A source that fails them should not enter the request.

Ask Before Generating

A reference map does not guarantee that every draft will remain consistent. It simply prevents the generation tool from settling decisions the team has not made.

The next time someone says, “Keep the cup blue,” ask one question first:

Which source confirms the blue?
