Color Ramp Widget



Color Ramps enables the user to specify a range of colors based on color-stops. Color-stops are similar to a mark indicating where exactly the chosen color should be. The interval from each of the color-stops added to the ramp is a result of the color interpolation and chosen interpolation method.


Add +
Clicking on this button will add a stop to your custom weight paint map. The stops are added from the last selected stop to the next one, from left to right and they will be placed in the middle of both stops.
Delete -
Deletes the selected color-stop from the list.
Flip <->
Flips the gradient, inverting the values of the custom weight paint range.
Color Mode

Selection of the color space used for interpolation.

Blends color by mixing each color channel and combining.
Blends colors by first converting to HSV or HSL, mixing, then combining again. This has the advantage of maintaining saturation between different hues, where RGB would de-saturate, this allows for a richer gradient.
Interpolation Options

Enables the user to choose the types of calculations for the color interpolation for each color stop.

Uses a B-Spline Interpolation for the color stops.
Uses a Cardinal Interpolation for the color stops.
Uses a Linear Interpolation for the color stops.
Uses a Ease Interpolation for the color stops.
Uses a Constant Interpolation for the color stops.
Active Color Stop
Index of the active color-stop (shown as a dashed line). Allows you to change the active color when colors may be too close to easily select with the cursor.
This slider controls the positioning of the selected color stop in the range.
Opens a color picker for the user to specify color and Alpha for the selected color stop. When a color is using Alpha, the Color button is then divided in two, with the left side showing the base color and the right side showing the color with the alpha value.
