Multi Color Mix

What's it for ?

Stack and blend several colors or decal textures in a single node — like a mini layer stack. Each layer has its own color, its own blend mode, and its own alpha, and the node gives you back the combined Color and a combined Alpha mask. Perfect for layering decals (logos, stickers, dirt, labels) over a base, or mixing a handful of colors without a spaghetti of Mix nodes.

Tip

Feed an Image Texture into a layer: its alpha is used automatically as the layer's mask (where the decal shows), and it also feeds into the node's Alpha output.

How the stack works

  • The top socket (base) is the background. It has no blend mode — it's simply what everything else sits on top of.
  • Each socket below is a layer painted over the ones above it, using its own blend mode. The lowest layer (just above the empty socket) ends up on top.
  • Connect anything to the empty socket at the bottom to add a new layer. Layers can be reordered (▲ / ▼) and removed (✕).

Per-layer controls

Each color layer has:

  • Color — the layer's color (or a label when a texture is plugged in). Its alpha (the color picker's A channel) sets how strongly the layer applies when no image is connected.
  • Blend — how this layer blends over the ones above (Mix, Multiply, Screen, Overlay, Add…). Not shown on the base layer.
  • ▲ / ▼ — move the layer up or down in the stack.
  • ✕ — delete the layer.

Note

A layer's alpha is taken from its connected image if there is one, otherwise from its color swatch. That alpha both masks the blend and feeds the Alpha output.

Node options

  • Alpha Mix — how every layer's alpha is combined into the Alpha output: Add (union / sum), Subtract, or Multiply (intersection).
  • Clamp — keep the resulting alpha within 0–1.

Outputs

  • Color — the final stacked color.
  • Alpha — the combined coverage of all layers (great to drive transparency, or as a mask downstream).

Setup Example

Plug a base color (or image) into the top socket, drop your decal images into the layers below, pick a blend per decal, and route Color + Alpha into your material.
