An interface should not rely only on colour to distinguish selected, failed or unavailable items. Labels, icons and focus shape can make the same state understandable to more viewers. If a player offers themes, choose one with clear contrast and non-colour cues. Check whether the state still makes sense when the hue difference is difficult to distinguish. A readable word, icon, shape or stable position can supply meaning that colour alone cannot, especially for focus, errors and unavailable items in a busy television interface.
Check actual states
Selection and errors deserve separate review. Review focused, selected, loading, failed and unavailable items separately, since each state communicates a different action or result. A coloured border can help locate focus but should remain recognizable against changing poster art. An error needs a useful message or symbol, not merely a red card. Describe what the viewer needs to know in each case, such as which item will open or why playback cannot begin, rather than treating every coloured indicator as the same design problem.
Avoid colour-only instructions
Press thegreen item can be ambiguous. Use instructions that name the control or its purpose instead of referring only to its colour. Select captions is clearer than select the green icon when the icon can change with the theme or the viewer cannot distinguish that hue. Where the interface itself uses a coloured badge, look for an accompanying label or recognizable shape. A stronger saturation setting may make colours vivid without adding the missing information needed to identify what the badge actually means.
Report specific barriers
Name the state and screen involved. Report the exact screen and state that is ambiguous, including what changes when focus moves or an error occurs. A privacy-checked screenshot can show that the only distinction is colour, while a short written description explains the resulting task barrier. Keep contrast concerns separate enough to identify them too: a labeled error may still be too faint to read. The developer can then address missing state meaning and poor visibility instead of receiving only a request to change the TV's colour preset.

An example to work through
An error icon and message communicate failure more clearly than a red outline alone. Two programme tiles differ only by a red or green dot, leaving availability unclear to a viewer who cannot distinguish them. Adding a readable available or unavailable label would communicate the state directly, whereas increasing the television's colour saturation would not explain what either dot means.
Questions about this topic
Does high saturation guarantee clarity?
No. Intensity cannot replace a missing label or a clear noncolour distinction between states.
Can aTV colour preset fix missing labels?
No. A display preset cannot create interface wording or symbols that the application never supplied.
