Create a shade-comparison sequence under consistent lighting

A repeatable shade comparison keeps the demonstration conditions steady while the product changes. Prepare the sequence before the live so the host does not move the light, reorder samples or lose track of shade names halfway through.

Build the comparison station

1. Mark one camera position and one sample position. Keep the same background and lighting throughout the comparison.
2. Label the samples before starting and arrange them in the intended presentation order.
3. Apply a comparable demonstration amount using the same method. State when a texture or format makes a direct comparison imperfect.
4. Show the samples together, then move closer without changing their order. Read each label as the corresponding sample is indicated.
5. Rehearse the reset between products so a used sample cannot be mistaken for a new shade.

Fictional worked example

In a fictional rehearsal, shade B is moved closer to a lamp than shade A. The team returns both to the marked positions and repeats that segment. The corrected recording supports a comparison under one setup; it does not prove that every viewer will see the same colour.

Next check

Watch the sequence without audio. The order and shade labels should remain understandable. Add a visible label where the identification depends entirely on speech.
