It’s good to study and think deeply about such things, but don’t be lulled into thinking you possess linear control over this particular aspect of “nature”.
In my view anyway, “design principles” are like flame, almost as though they don’t exist, until they exist, and then they may snuff out at any time, depending on surrounding conditions. You have some in your mind, and you may attempt to apply them with varying degrees of success, but potentially unforeseen context could cause a shift in their effectiveness later during the life of the design.
We all want to put solid controls on our work and everything we see. So someone may critique your print design and express a dislike for certain color combinations. But, had they viewed it under halogen lighting rather than LED, their perception of it may have been markedly different. Or, perhaps the migraine they’re getting over has left them sensitive to visual tension. So the principles you applied, the ones they applied, and the prevailing conditions, can at any time result in an uncertain “quotient” — a flame was there, until it wasn’t. You can strike the match, but you can’t control the wind.
