# Links

> Understand connection links in ComfyUI

## Links connect nodes

In ComfyUI, the lines or curves drawn between nodes are called ***links*** (also referred to as ***connections*** or wires). They carry data from one node's output to another node's input, defining the flow of your workflow.

Links can be displayed in several visual styles: curves, right angles, straight lines, or hidden entirely.

To change the link style, go to **Setup Menu** → **Display (Lite Graph)** → **Graph** → **Link Render Mode**.

You can also temporarily hide all links from the **Canvas Menu**.

<Tip>
  Showing links is especially useful when learning, sharing, or debugging a workflow — they make the data flow visible at a glance. For finished workflows that aren't meant to be edited, hiding links can reduce visual clutter.

### Reroute node

When a workflow becomes complex, link wires can overlap or pass behind nodes, making it hard to read. The **Reroute** node lets you manually redirect a wire through any point in the 2D graph space, keeping the layout clean and legible.

ComfyUI also has a built-in native reroute feature in the graph canvas. We recommend using this for new workflows.

## Color-coding

Every data type in ComfyUI has a distinct color. Node input and output ports, as well as the link wires connecting them, all share this color scheme. **You can only connect ports of the same color** — this ensures type safety across your workflow.
