Ignoring the title at first, the only thing solvers are presented with is a selection of trigrams and the occasional bigram/single letter, grouped into 28 sets of up to 14 alphabetically-sorted fragments. These sets are colored in one of 16 distinct ways, with some colors repeating.
As is the case with most trigram-based puzzles, the first step is the rearrange each set into a sentence that makes sense. Two such results are "LET NOT LIG HTS EEM YBL ACK AND DEE PDE SIR ESI" and "IDR EAM TLA STN IGH TOF THE THR EEW EIR DPS IST ERS". As solvers put these together, they will hopefully notice two things. First, that all of the sentences are direct quotes from Macbeth, a play by William Shakespeare that is often referred to as "The Scottish Play" to avoid saying its (reportedly) cursed name. Second, each of the completed rearrangements has a single extra letter inserted into them (The letter I at the end of the first example, and the letter P in the second between "weird" and "sisters").
Upon further investigation, solvers may also notice that each of the quotes is from a different one of the 28 scenes of Macbeth, thereby providing an ordering for the extra letters. Those letters spell out the phrase "APPLY APPROPRIATE COLORCHECKER". With a bit of a research, solvers should discover that ColorChecker's Color Rendition Chart was originally known as the Macbeth ColorChecker, and all of the colors used in the puzzle are also present in it.
Armed with this information, solvers can then assign a letter of the alphabet (A-X) to each of the colors in the ColorChecker in reading order, and use it as a way to extract a new single letter from each of the trigram sets (retaining the ordering determined by the Shakespeare lines). Doing so, the phrase "NAME OF SW PAINT SIX TWO THREE FOUR" will be extracted.
