Color node icon   Color (node)

An RGBA color source that outputs the color as a vector.

Color node diagram

The Color node holds a color and hands it to the node graph. Its most common job is tinting geometry: wire it into a Style node's Fill or Stroke input, and the geometry that flows through - including whatever a downstream Preview shows in the Modeling window - takes that color.

The color picker

Double-click the node's swatch to open the full color picker. Every control is linked to the same color - move any one and the rest update to match.

The Color node's picker: a hue-saturation wheel with a marker, a vertical lightness slider, and a live preview swatch across the top; then H, S, L, R, G, B, and A rows each with a gradient slider and a number field; and a Hex field with a Done button at the bottom.

  • Hue-saturation wheel: click or drag the marker to set the color. Angle around the wheel is the hue; distance from the center is the saturation (center = grey, rim = fully saturated).
  • Lightness slider (the vertical bar beside the wheel): dark at the bottom, light at the top. The wheel repaints to show that slice of lightness.
  • Preview swatch: the large panel on the right shows the current color, including its transparency.
  • H | S | L: Hue (0-360 degrees), Saturation (0-100%), Lightness (0-100%). Each has a slider and a number field you can type into.
  • R | G | B: the Red, Green, and Blue channels (0-255) - the same color expressed as screen primaries.
  • A: Alpha, the opacity from 0 (fully transparent) to 100% (fully opaque).
  • Hex: the six-digit hex code. Read it off, or type one in to jump straight to a color.
  • Done: closes the picker; the node keeps whatever color you left it on.

Outputs

  • Color: the chosen color, carried as a vector (RGBA) other nodes can read.

Tip

A Color node only holds a color - the Style node is what applies it to geometry. Add a Style before you Realize and the color bakes into the model.
