You missed my point, which was that the example was supposed to show how changes in hue affected whether something would look good, but the example showed dramatically varying lightness and chroma, in addition to the hue differences, thus making the comparison useless as a demonstration of the claimed effect. To make an example showing what the author of these examples wants to show, it would be necessary to keep lightness and chroma consistent from one set of color combinations to another, so that viewers can see the hue differences instead of being distracted by lightness&#x2F;chroma differences.<p>If the “Müller formula” worked the way the author of these example images thought, then the color combinations at the right side after my lightness switcharound should <i>still</i> be “good looking”, but to me at least, with low lightness contrast, they instead start to look very muddy. Likewise, in my opinion the color combinations at the left of each example are improved dramatically by the increase in lightness contrast, even though they still have low chroma contrast and aren’t exactly my favorites.
