Enum ColorStopBlendMode

Per-segment color blend operator applied between a ColorGradientStop and its successor. Replaces the default straight-line interpolation with a physically-motivated combine of the two endpoint colors.

Namespace: Scylla.Core.Util.Palette
Assembly: ScyllaCore.dll
Syntax
public enum ColorStopBlendMode
Remarks

Unlike a Photoshop layer blend (which composites a top layer onto a fixed base), a stop-to-stop blend interpolates *between* two colors along the gradient's local t parameter. The result is a path through color space whose shape is determined by the operator: linear interpolation toward an endpoint for Normal, toward the channelwise product for Multiply, toward the inverse product for Screen, and toward the linear-light sum for Add.

Blend operators other than Normal compute their result in linear-light space (sRGB transfer applied/removed at the boundaries) so the curve respects how light actually combines. Endpoints round-trip exactly: Blend(a, b, 0) == a and Blend(a, b, 1) == b for every mode.

Blend modes compose with (run after) the per-stop ColorGradientStopInterpolation easing curve and Midpoint: the easing reshapes t, then the blend operator consumes the reshaped t together with the two endpoint colors to produce the final segment color.

Fields

Name Description
Add

Linear-light additive blend, clamped to [0, 1]. The segment passes through min(1, a + b) per channel. Pushes the midpoint toward the brightest mixture of both colors; useful for HDR and blackbody ramps where the midtone should glow rather than stay perceptually between the two endpoints.
Multiply

Linear-light multiply blend. The segment passes through the channelwise product of the two endpoint colors. Produces darker, more saturated midtones; useful for lava ramps, organic shadow ramps, and dye-style color mixing.
Normal

Plain straight-line interpolation between the two endpoint colors in the gradient's configured color space (RGB, HSV, or Oklab). The default.
Screen

Linear-light screen blend (inverse multiply). The segment passes through 1 - (1 - a) * (1 - b) per channel. Produces brighter, washed-out midtones; useful for glow / bloom hot tails and additive light ramps.
