Short journal · Original editorial · Useful disagreement
A design discussion turns into a contest between favourite colours.
Agreement is easier to assess when the actual choice is visible. A disagreement can concern evidence, preference, timing, or limits. Name the point of difference before trying to settle it, and leave people room to revise their view.
Test the colours against the actual reading task.
Do not confuse a tidy description with a useful result. Look at what the next reader or participant can actually do.
