Screenshots - Color blending
The first time you tap the Blend icon this first screen appears.
Just drag an existing palette color onto the start and end chips or double-tap the start or end chip to select a color.
Once both are set the colors will be blended. You may have 1, 2, or 3 blended colors generated. Use the slider to adjust the blend weighting.
This shows the user dragging one of the new colors onto an existing palette color. This will replace the color.
