Animating Colors

When a solid fill color is keyframed at two different values, FlashFX interpolates between them through LAB color space by default. LAB interpolation produces perceptually uniform transitions — the brightness appears consistent throughout the transition, which avoids the muddy midpoints that can occur with RGB-space interpolation.

Alternative: RGB interpolation — selectable via the color track context menu. RGB interpolation passes through the RGB midpoint, which can produce unintended hue shifts in the middle of the transition.

Gradients can be keyframed in several ways:

• -Stop Color — the color of a specific gradient stop changes over time
• -Stop Position — a stop moves along the gradient ramp over time
• -Gradient Angle — the direction of the gradient rotates over time
• -Center Position (radial) — the gradient's center point moves over time

Animating gradient stop positions creates color band animation effects — color zones sweep across the element.

A fast two-keyframe color animation (Hold type keyframes) over 1 to 2 frames creates a hard color flash or strobe effect. This is commonly used for:

• -Impact flashes on beat hits
• -Glitch color effects
• -Notification pulse effects
