An indicator on a device changes from red to green, and the film cuts to someone leaving. For a person familiar with the device, this may be a clear change of state. A first-time viewer must infer both the color and what it means.
Product videos can retain the immediacy of color while adding text, shape or an observable result to important information. The goal is to explain the device's state without turning the film into a complicated technical manual.
A color is not yet an explanation
Imagine a fictional air purifier whose indicator is red while starting and green when ready. Even a beautiful image leaves an unfamiliar viewer guessing if the narration says only “wait for the color to change.” Red and green may mean different things on different products; the brand's intended status cannot be assumed.
Confirm each state, the position of the light and the device's actual feedback with the product team. Then write what the viewer needs to understand: for example, “Preparing,” followed by “Ready to begin.” The words must correspond to the real device and not imply a capability it lacks.
Give status more than one visual cue
The W3C's WCAG 2.2 success criterion 1.4.1 says color should not be the only visual way to convey information in web content. Applying that idea to product video is a creative and readability approach; adding captions alone does not prove that a whole page or video meets every accessibility requirement.
A close-up can pair the indicator with concise status text. An animated sequence can distinguish stages with different shapes and labels. A live-action demonstration can show an actual outcome, such as a lid clicking shut or a confirmed completion message. Each approach has limits: tiny text can be unreadable, abstract icons may need explanation, and an action may not reveal the device's internal state.
Keep the real color and consider the small screen
Text should explain the real indicator, not disguise a filming error. Check whether the light is clipped, lost in reflections or difficult to locate in the frame. If the grade changes the apparent state, compare it with the sample and approved product information.
Review the cut on a phone: does a finger cover the light, does the label obscure the operation, and is there enough time to read it? Ask people with different levels of familiarity to explain the current state and next step. A small review can reveal obvious gaps; it does not represent every viewer or certify accessibility.
Give sound and text complementary roles
If the device makes an actual signal, preserve it where useful and describe meaningful sound in captions or a transcript. Do not assume everyone can hear the signal, or add an effect that might be mistaken for the product's actual sound. Watching silently and listening without the picture are different checks: one tests visual information, the other can reveal missing directions or status in the narration.
When a complex operation cannot be explained in the existing narration, explore ONCE video marketing insights and consider added description or another version. Color cues work with image, text and sound to answer the same question.
If you are planning a product demonstration or multilingual video, contact ONCE to discuss status feedback and visual storytelling.
