Color

All properties and functions that expect color values in the form of instances of Color objects, also accept named colors and hex values as strings which are then converted to instances of Color internally.

Example: Named color values:

// Create a circle shaped path at {x: 80, y: 50}
// with a radius of 30.
var circle = new Path.Circle(new Point(80, 50), 30);

// Pass a color name to the fillColor property, which is internally
// converted to a Color.
circle.fillColor = 'green';

Example: Hex color values:

// Create a circle shaped path at {x: 80, y: 50}
// with a radius of 30.
var circle = new Path.Circle(new Point(80, 50), 30);

// Pass a hex string to the fillColor property, which is internally
// converted to a Color.
circle.fillColor = '#ff0000';

// Create a rectangle shaped path between
// the topLeft and bottomRight points:
var path = new Path.Rectangle(topLeft, bottomRight);

// Create the gradient, passing it an array of colors to be converted
// to evenly distributed color stops:
var gradient = new Gradient(['yellow', 'red', 'blue']);

// Have the gradient color run between the topLeft and
// bottomRight points we defined earlier:
var gradientColor = new Color(gradient, topLeft, bottomRight);

// Set the fill color of the path to the gradient color:
path.fillColor = gradientColor;

Example:Applying a radial gradient color containing unevenly distributed color stops:

// Create a circle shaped path at the center of the view
// with a radius of 80:
var path = new Path.Circle({
    center: view.center,
    radius: 80
});

// The stops array: yellow mixes with red between 0 and 15%,
// 15% to 30% is pure red, red mixes with black between 30% to 100%:
var stops = [
    ['yellow', 0],
    ['red', 0.15],
    ['red', 0.3],
    ['black', 0.9]
];

// Create a radial gradient using the color stops array:
var gradient = new Gradient(stops, true);

// We will use the center point of the circle shaped path as
// the origin point for our gradient color
var from = path.position;

// The destination point of the gradient color will be the
// center point of the path + 80pt in horizontal direction:
var to = path.position + [80, 0];

// Create the gradient color:
var gradientColor = new Color(gradient, from, to);

// Set the fill color of the path to the gradient color:
path.fillColor = gradientColor;
