stop-color : SVG Gradient Stop Color Property

The stop-color property specifies the color value at a gradient stop within SVG gradient definitions. This property is essential for creating linear and radial gradients by defining the colors at specific positions along the gradient vector.

Usage

selector {
    stop-color: value;
}

The stop-color property accepts color values in various formats to define the color at a specific gradient stop.

Supported Values

Named Colors

Standard CSS color names such as red, blue, green, black, orange, etc.

Hexadecimal Colors

Short form: #RGB (e.g., #f00 for red)
Long form: #RRGGBB (e.g., #ff0000 for red)

RGB/RGBA Functions

RGB: rgb(red, green, blue) where values are 0-255
RGBA: rgba(red, green, blue, alpha) where alpha is 0.0-1.0

HSL/HSLA Functions

HSL: hsl(hue, saturation%, lightness%)
HSLA: hsla(hue, saturation%, lightness%, alpha)

Special Keywords

currentColor - Uses the current color value of the element

Supported Elements

The stop-color property applies to:

<stop> elements within <linearGradient> definitions
<stop> elements within <radialGradient> definitions

Note: This property only works on <stop> elements, not on shape elements directly.

Notes

Must be used within <stop> elements inside gradient definitions
Each <stop> element defines a color at a specific offset (0% to 100%)
Multiple stops create color transitions in gradients
The offset attribute determines where the color appears in the gradient
Gradients interpolate colors between stops
Use with stop-opacity for transparent gradient stops
Default stop-color is typically black if not specified
Gradients are reusable and can be referenced by multiple elements
Essential for creating smooth color transitions in backgrounds, fills, and shapes
Vector gradients maintain quality at any zoom level in PDF viewers
Can create complex multi-color gradients with multiple stops

Data Binding

The stop-color property can be dynamically controlled through data binding, enabling data-driven gradient colors that respond to values, states, or categories. This is essential for creating dynamic visualizations with color-coded data representations.

Example 1: Data-driven gradient colors for status indicators

<style>
    .status-bar { fill: url(#statusGrad); }
</style>
<body>
    <svg width="400" height="150" xmlns="http://www.w3.org/2000/svg">
        <defs>
            <template data-bind="">
                <linearGradient id="statusGrad" x1="0%" y1="0%" x2="100%" y2="0%">
                    <stop offset="0%" stop-color=""/>
                    <stop offset="100%" stop-color=""/>
                </linearGradient>
            </template>
        </defs>
        <rect class="status-bar" width="400" height="150"/>
    </svg>
</body>

Example 2: Dynamic multi-stop gradients from data

<style>
    .data-viz { fill: url(#dataGradient); }
</style>
<body>
    <svg width="500" height="300" xmlns="http://www.w3.org/2000/svg">
        <defs>
            <linearGradient id="dataGradient" x1="0%" y1="0%" x2="0%" y2="100%">
                <template data-bind="">
                    <stop offset="%" stop-color=""/>
                </template>
            </linearGradient>
        </defs>
        <rect class="data-viz" width="500" height="300"/>
    </svg>
</body>

Example 3: Conditional gradient colors based on thresholds

<style>
    .metric-bar { fill: url(#metricGrad); }
</style>
<body>
    <svg width="400" height="100" xmlns="http://www.w3.org/2000/svg">
        <defs>
            <template data-bind="">
                <linearGradient id="metricGrad" x1="0%" y1="0%" x2="100%" y2="0%">
                    <stop offset="0%" stop-color="#ef4444#f59e0b#10b981"/>
                    <stop offset="100%" stop-color="#dc2626#d97706#059669"/>
                </linearGradient>
            </template>
        </defs>
        <rect class="metric-bar" x="25" y="25" width="350" height="50" rx="25"/>
    </svg>
