Each answer is used in three ways:

• Each answer solves one of the clues given at the bottom of the metapuzzle.
• Each answer can be associated with one of the colors in the "Titles" section; moreover, these colors correspond to characters in the board game Clue. The letter in each color appears in that character's title (according to the 2023 edition of the game).
• Finally, each answer can be associated with one of the weapons in Clue (again using the 2023 edition).

To extract the answer, find the position of the given letters in each title, and extract the letter in that position for each weapon:

Clue	Answer	Given color/letter	Clue character	Weapon
fancy	WHITE TIE	C	CHEF WHITE	ROPE
surprise	BOLT FROM THE BLUE	L	SOLICITOR PEACOCK	WRENCH
Prince	PURPLE RAIN	F	PROFESSOR PLUM	LEAD PIPE
meet expectations	CUT THE MUSTARD	C	COLONEL MUSTARD	DAGGER
inflamed	BLOODSHOT	I	MISS SCARLET	REVOLVER
go	GREENLIGHT	Y	MAYOR GREEN	CANDLESTICK

Reading those letters from the weapons gives the answer to the effect on the decor, REDDEN.
