Yellow
Attention — warmth, warning, and the colour that asks to be seen.
Yellow in a dream is the dictionary's image of attention itself. The dream often uses yellow on something it wants you specifically to notice. The folk meaning is mixed — warmth and warning both — and the dream sometimes uses the doubleness deliberately.
Where you often see it. A yellow flower. A yellow warning light. A yellow piece of paper asking for attention. The dream uses yellow when something needs to be seen — sometimes welcoming, sometimes cautionary.
What it is not. Yellow is not cowardice in the dictionary's register. That overlay is cultural; the dream's yellow is warmth that asks for your gaze.
Related in the dictionary. Read yellow with sun, light, attention contexts, and warm gatherings. Pair with red when intensity is also present and the dream wants you to track the difference.
