# set_fill_color

> Set the fill color of a node in Figma

Sets the fill color of a Figma node. Works with text nodes and frame nodes.

## Parameters

<ParamField path="nodeId" type="string" required>
  The ID of the node to modify
</ParamField>

<ParamField path="r" type="number" required>
  Red component (0-1 range)
</ParamField>

<ParamField path="g" type="number" required>
  Green component (0-1 range)
</ParamField>

<ParamField path="b" type="number" required>
  Blue component (0-1 range)
</ParamField>

<ParamField path="a" type="number">
  Alpha/transparency component (0-1 range). Defaults to 1 (fully opaque)
</ParamField>

<Note>
  Figma uses RGBA values in the 0-1 range, not 0-255. For example, pure red is `{r: 1, g: 0, b: 0}`, not `{r: 255, g: 0, b: 0}`.
</Note>

## Response

Returns the name of the modified node and confirms the color change.
