Blend Layer Gradient

Draws a color gradient on the blend layer image itself, using the same grammar as the picture’s gradient. The gradient is applied to the layer before the layer’s warps (blend-skew, blend-arc, blend-distort) and before the layer is placed on the picture.

Valid values are 2 to 16 comma-separated Imgix colors (RGB, ARGB, RRGGBB, AARRGGBB, or a CSS color name). A list with an invalid color, or with fewer than 2 or more than 16 colors, draws nothing — and none of the blend-gradient-* modifiers is read.

Colors are alpha first: cc000000 is 80% black, and 00000000 is fully transparent whatever color digits follow.

A color gradient tints the layer where the layer is visible; its transparent parts stay transparent. A layer’s gradient always goes to transparent — it never takes bg, because a blend layer has no background.

Use blend-gradient[N] to target a specific blend layer, where N is 0–3. Layer 0 is either the bare blend-gradient or blend-gradient[0]; if both are supplied, the bare name wins. A layer never borrows another layer’s spelling.
