Value

A CSS color value.

Additional attributes

In addition to the global attribute and the input attributes common to all <input> elements, the color input also supports the following attributes:

alpha Experimental

A boolean attribute, if present, indicates the color's alpha component can be manipulated by the end user and does not have to be fully opaque.

colorspace Experimental

Defines the color space for the color and hints at the desired user interface for the color picker widget. Possible enumerated values are:

• "limited-srgb": The color is in the must be provided color space. This includes rgb(), hsl(), hwb(), and <hex-color> values. The color value is limited to 8-bits per r, g, and b component. This is the default.
• "display-p3": The Display P3 color space, e.g., color(display-p3 1.84 -0.19 0.72 / 0.6)

Using color inputs

Inputs of type color are simple, due to the limited number of attributes they support.

Providing a default color

You can update the example above to set a default value, so that the color picker is pre-filled with the default color and the color picker (if any) will also default to that color.

<input type="color" value="#ff0000" />
<input
  type="color"
  id="body"
  name="body"
  value="oklab(50% 0.1 0.1 / 0.5)"
  colorspace="display-p3"
  alpha />

If you don't specify a value or if the value is invalid or otherwise not supported by the browser, the value defaults to #000000, which is opaque black.

Tracking color changes

As is the case with other <input> types, there are two events that can be used to detect changes to the color value: input and change. input is fired on the <input> element every time the color changes. The change event is fired when the user dismisses the color picker. In both cases, you can determine the new value of the element by looking at its value.

Here's an example that watches changes over time to the color value:

colorPicker.addEventListener("input", updateFirst, false);
colorPicker.addEventListener("change", watchColorPicker, false);

function watchColorPicker(event) {
  document.querySelectorAll("p").forEach((p) => {
    p.style.color = event.target.value;
  });
}

Selecting the value

When a browser doesn't support a color picker interface, its implementation of color inputs will be a text box that validates the contents automatically to ensure that the value is in the correct format. In this case you can use the select() method to select the text currently in the edit field.

If the browser instead uses a color picker, select() does nothing. You should be aware of this behavior so your code can respond appropriately in either case.

colorPicker.select();

Validation

A color input's value is considered to be invalid if the user agent is unable to convert the user's input into seven-character lower-case hexadecimal notation. If and when this is the case, the :invalid pseudo-class is applied to the element.

Example

Let's create an example which does a little more with the color input by tracking the change and input events to take the new color and apply it to every <p> element in the document.

HTML

The HTML is fairly straightforward — a couple of paragraphs of descriptive material with an <input> of type color with the ID color-picker, which we'll use to change the color of the paragraphs' text.

<p>
  An example demonstrating the use of the
  <code>&lt;input type="color"&gt;</code> control.
</p>

<label for="color-picker">Color:</label>
<input type="color" value="#ff0000" id="color-picker" />

<p>
  Watch the paragraph colors change when you adjust the color picker. As you
  make changes in the color picker, the first paragraph's color changes, as a
  preview (this uses the <code>input</code> event). When you close the color
  picker, the <code>change</code> event fires, and we detect that to change
  every paragraph to the selected color.
</p>

JavaScript

First, there's some setup. Here we establish some variables, setting up a variable that contains the color we'll set the color picker to when we first load up, and then setting up a load handler to do the main startup work once the page is fully loaded.

let colorPicker;
const defaultColor = "#0000ff";

window.addEventListener("load", startup, false);

Initialization

Once the page is loaded, our load event handler, startup(), is called:

function startup() {
  colorPicker = document.querySelector("#color-picker");
  colorPicker.value = defaultColor;
  colorPicker.addEventListener("input", updateFirst, false);
  colorPicker.addEventListener("change", updateAll, false);
  colorPicker.select();
}

This gets a reference to the color <input> element in a variable called colorPicker, then sets the color input's value to the value in defaultColor. Then the color input's input event is set up to call our updateFirst() function, and the change event is set to call updateAll(). These are both seen below.

Finally, we call select() to select the text content of the color input if the control is implemented as a text field (this has no effect if a color picker interface is provided instead).

Reacting to color changes

We provide two functions that deal with color changes. The updateFirst() function is called in response to the input event. It changes the color of the first paragraph element in the document to match the new value of the color input. Since input events are fired every time an adjustment is made to the value (for example, if the brightness of the color is increased), these will happen repeatedly as the color picker is used.

function updateFirst(event) {
  const p = document.querySelector("p");
  if (p) {
    p.style.color = event.target.value;
  }
}

When the color picker is dismissed, indicating that the value will not change again (unless the user re-opens the color picker), a change event is sent to the element. We handle that event using the updateAll() function, using Event.target.value to obtain the final selected color:

function updateAll(event) {
  document.querySelectorAll("p").forEach((p) => {
    p.style.color = event.target.value;
  });
}

This sets the color of every <p> block so that its color attribute matches the current value of the color input, which is referred to using event.target.

Result

The final result looks like this:
