CSS Colors

CSS supports 140+ color names, HEX values, RGB values, RGBA values, HSL values, HSLA values, and opacity.

RGBA Colors

RGBA color values are an extension of RGB color values with an alpha channel — which specifies the opacity for a color.

An RGBA color value is specified with: rgba(red, green, blue, alpha). The alpha parameter is a number between 0.0 (fully transparent) and 1.0 (fully opaque).

The following example defines different RGBA colors:

Example

HSL Colors

HSL stands for Hue, Saturation and Lightness.

An HSL color value is specified with: hsl(hue, saturation, lightness).

Hue is a degree on the color wheel (from 0 to 360):
- 0 (or 360) is red
- 120 is green
- 240 is blue
Saturation is a percentage value: 100% is the full color.
Lightness is also a percentage; 0% is dark (black) and 100% is white.

The following example defines different HSL colors:

Example

HSLA Colors

HSLA color values are an extension of HSL color values with an alpha channel — which specifies the opacity for a color.

An HSLA color value is specified with: hsla(hue, saturation, lightness, alpha), where the alpha parameter defines the opacity. The alpha parameter is a number between 0.0 (fully transparent) and 1.0 (fully opaque).

The following example defines different HSLA colors:

Example

Opacity

The CSS opacity property sets the opacity for the whole element (both background color and text will be opaque/transparent).

The opacity property value must be a number between 0.0 (fully transparent) and 1.0 (fully opaque).

Notice that the text above will also be transparent/opaque!

The following example shows different elements with opacity:

The CSS data type represents a color. A may also include an alpha-channel transparency value, indicating how the color should composite with its background.

Note: Although values are precisely defined, their actual appearance may vary (sometimes significantly) from device to device. This is because most devices are not calibrated, and some browsers do not support output devices’ color profiles.

Syntax

/* Named colors */ rebeccapurple aliceblue /* RGB Hexadecimal */ #f09 #ff0099 /* RGB (Red, Green, Blue) */ rgb(255 0 153) rgb(255 0 153 / 80%) /* HSL (Hue, Saturation, Lightness) */ hsl(150 30% 60%) hsl(150 30% 60% / 0.8) /* HWB (Hue, Whiteness, Blackness) */ hwb(12 50% 0%) hwb(194 0% 0% / 0.5) /* LAB (Lightness, A-axis, B-axis) */ lab(50% 40 59.5) lab(50% 40 59.5 / 0.5) /* LCH (Lightness, Chroma, Hue) */ lch(52.2% 72.2 50) lch(52.2% 72.2 50 / 0.5) /* Oklab (Lightness, A-axis, B-axis) */ oklab(59% 0.1 0.1) oklab(59% 0.1 0.1 / 0.5) /* Oklch (Lightness, Chroma, Hue) */ oklch(60% 0.15 50) oklch(60% 0.15 50 / 0.5)

A value can be specified using one of the methods listed below:

By keywords: (such as blue or pink ), , and currentcolor .
By hexadecimal notations: (such as #ff0000 ).
By parameters in a color space using functional notations:
- sRGB color space: hsl() , hwb() , rgb() ;
- CIELAB color space: lab() , lch() ;
- Oklab color space: oklab() , oklch() ;
- Other color spaces: color() .
currentcolor keyword

The currentcolor keyword represents the value of an element’s color property. This lets you use the color value on properties that do not receive it by default.

If currentcolor is used as the value of the color property, it instead takes its value from the inherited value of the color property.
```
div style="color: blue; border: 1px dashed currentcolor;"> The color of this text is blue. div style="background: currentcolor; height:9px;">div> This block is surrounded by a blue border. div> 
```
Missing color components

Each component of any CSS color functions — except for those using the legacy comma-separated syntax — can be specified as the keyword none to be a missing component.

Explicitly specifying missing components is useful in color interpolation for cases where you would like to interpolate some color components but not others. For all other purposes, a missing component will effectively have a zero value in an appropriate unit: 0 , 0% , or 0deg . For example, the following colors are equivalent when used outside of interpolation:
```
/* These are equivalent */ color: oklab(50% none -0.25); color: oklab(50% 0 -0.25); /* These are equivalent */ background-color: hsl(none 100% 50%); background-color: hsl(0deg 100% 50%); 
```
Interpolation

Color interpolation happens with gradients, transitions, and animations.

When interpolating values, they are first converted to a given color space, and then each component of the computed values are interpolated linearly, with interpolation’s speed being determined by the easing function in transitions and animations. The interpolation color space defaults to Oklab, but can be overridden through in some color-related functional notations.

Interpolation with missing components

Interpolating colors in the same space

When interpolating colors that are exactly in the interpolation color space, missing components from one color are replaced with existing values of the same components from the other color. For example, the following two expressions are equivalent:
```
color-mix(in oklch, oklch(none 0.2 10), oklch(60% none 30)) color-mix(in oklch, oklch(60% 0.2 10), oklch(60% 0.2 30)) 
```
Note: If a component is missing from both colors, this component will be missing after the interpolation.

Interpolating colors from different spaces: analogous components

If any color to be interpolated is not in the interpolation color space, its missing components are transferred into the converted color based on analogous components of the same category as described in the following table:

Category Analogous components

Reds R , X

Greens G , Y

Blues B , Z

Lightness L

Colorfulness C , S

Hue H

a a

b b
- X ( 0.2 ) in color(xyz 0.2 0.1 0.6) is analogous to R ( 50% ) in rgb(50% 70% 30%) .
- H ( 0deg ) in hsl(0deg 100% 80%) is analogous to H ( 140 ) in oklch(80% 0.1 140) .
Using Oklch as the interpolation color space and the two colors below as an example:
```
lch(80% 30 none) color(display-p3 0.7 0.5 none) 
```
the preprocessing procedure is:
```
lch(80% 30 0) color(display-p3 0.7 0.5 0) 
```
```
oklch(83.915% 0.0902 0.28) oklch(63.612% 0.1522 78.748) 
```
```
oklch(83.915% 0.0902 none) oklch(63.612% 0.1522 78.748) 
```
```
oklch(83.915% 0.0902 78.748) oklch(63.612% 0.1522 78.748) 
```
Accessibility considerations

Some people have difficulty distinguishing colors. The WCAG 2.2 recommendation strongly advises against using color as the only means of conveying a specific message, action, or result. See color and color contrast for more information.

Examples

Color value tester

In this example we provide a and a text input. Entering a valid color into the input causes the to adopt that color, allowing you to test our color values.

HTML
```
div>div> hr /> label for="color">Enter a valid color value:label> input type="text" id="color" /> 
```
```
div  height: 200px; width: 200px; > 
```
```
const inputElem = document.querySelector("input"); const divElem = document.querySelector("div"); function validTextColor(stringToTest)  if (stringToTest === "inherit" || stringToTest === "transparent")  return false; > const div = document.createElement("div"); div.style.color = stringToTest; return !!div.style.color; > inputElem.addEventListener("input", () =>  if (validTextColor(inputElem.value))  divElem.style.backgroundColor = inputElem.value; divElem.textContent = ""; > else  divElem.removeAttribute("style"); divElem.textContent = "Invalid color value"; > >); 
```
