What the four colors actually mean
Every Connections puzzle sorts its 16 words into four groups of four, color-coded by difficulty: yellow is the easiest and most literal, green is a step trickier, blue is harder still, and purple is the most devious — usually built on wordplay, hidden words, or a twist you only see in hindsight.
The colors are a difficulty ranking, not a hint about content. Knowing the order matters because the puzzle is designed so the “obvious” grouping is often a decoy that steals a word from a harder category.
