What to change
Ask your supplier to check every button appearance against its real background, including pointer, keyboard and pressed states.
A worked example
Illustrative example
An outlined action fills with the brand colour on hover while its text changes to a readable contrasting colour and its focus remains visible.
Why this matters to your practice
A button changes appearance as people point to it, select it or reach it by keyboard. Its label must remain readable in every state. Ask your supplier to demonstrate those changes against the backgrounds used on the finished site, including photographs or coloured panels. A design sample on a white page may miss the problem. Review secondary actions as well as the main booking button, because people need to read Cancel, Back and Change just as confidently.
A practical review example
An outlined contact button may fill with a brand colour when selected but keep text designed for its original pale background. Ask your supplier to demonstrate that transition rather than review only a static colour palette. Include buttons on photographs and coloured panels, then try a touch device where hover behaviour differs. The wording and current keyboard marker should remain clear. Approval should cover secondary actions such as Back and Cancel too, because those are part of a visitor's ability to correct or leave a task.
How to check the result
Accept when interaction never reduces a usable control to an unreadable label and all supported states remain distinguishable.
A mistake to avoid
Reviewing only the colour palette swatches misses combinations introduced by state transitions in the actual interface.
