In reality, a particular shade of a color, say pink, can look darker when surrounded by some colors, lighter when surrounded by another, crisp in one context, and difficult to read in another. Picking one absolute value for it doesn’t actually deliver what it’s supposed to: consistency. The job of the good designer is to deliver a great design based on context. If the goal is consistency, then the designer should have the freedom to adjust that color to get that to happen, again working back from the context to the solution.
