The CanvasRenderingContext2D.fillStyle property of the Canvas 2D API specifies the color, gradient, or pattern to use inside shapes. The default style is #000 (black).

For more examples of fill and stroke styles, see Applying styles and color in the Canvas tutorial.


ctx.fillStyle = color;
ctx.fillStyle = gradient;
ctx.fillStyle = pattern;


A DOMString parsed as CSS <color> value.
A CanvasGradient object (a linear or radial gradient).
A CanvasPattern object (a repeating image).


Changing the fill color of a shape

This example applies a blue fill color to a rectangle.


<canvas id="canvas"></canvas>


const canvas = document.getElementById('canvas');
const ctx = canvas.getContext('2d');

ctx.fillStyle = 'blue';
ctx.fillRect(10, 10, 100, 100);


Creating multiple fill colors using loops

In this example, we use two for loops to draw a grid of rectangles, each having a different fill color. To achieve this, we use the two variables i and j to generate a unique RGB color for each square, and only modify the red and green values. (The blue channel has a fixed value.) By modifying the channels, you can generate all kinds of palettes.

const canvas = document.getElementById('canvas');
const ctx = canvas.getContext('2d');

for (let i = 0; i < 6; i++) {
  for (let j = 0; j < 6; j++) {
    ctx.fillStyle = `rgb(
        ${Math.floor(255 - 42.5 * i)},
        ${Math.floor(255 - 42.5 * j)},
    ctx.fillRect(j * 25, i * 25, 25, 25);

The result looks like this:

In WebKit- and Blink-based browsers, the non-standard and deprecated method ctx.setFillColor() is implemented in addition to this property.

setFillColor(color, optional alpha);
setFillColor(grayLevel, optional alpha);
setFillColor(r, g, b, a);
setFillColor(c, m, y, k, a);
