Prompt Palette is an add-on node for ComfyUI, a visual, node-based tool used to build AI image generation workflows. It replaces the plain text box where you normally type your image prompt with a more capable editor built around wildcards, which are placeholder terms surrounded by double underscores, like a style or lighting choice, that get randomly filled in from a saved list of options when the image is generated. Each wildcard in your prompt is automatically colored according to the folder it belongs to, so you can tell at a glance whether a term is a style pick, a character pick, or something else, and a small legend below the prompt lists every color in use. If a wildcard does not match anything saved in your library, perhaps because it was mistyped, renamed, or moved, it is shown in red with a dashed underline instead, and a counter tracks how many wildcards are working versus missing. A side drawer lets you browse, search, and insert wildcards without leaving the node, pin favorites to the top of the list, see your recently used ones, and preview what a wildcard file contains just by hovering over it. You can also create or edit wildcard files directly inside ComfyUI, save custom prompt combinations as reusable presets, and store prompts you want to reuse later. By default the node behaves like an ordinary prompt box and works without any extra setup. If you want more control, optional inputs and outputs can be turned on individually in the settings, including connecting a model and CLIP encoder for live prompt encoding, automatic loading of LoRA files, a negative prompt field, and a fixed seed input. The interface also supports light and dark themes, custom fonts, and adjustable color and text size settings.
