What html color is that

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:

  Replace the missing components in both colors with a zero value:

  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"; > >);

  HTML Colors

  HTML colors are specified with predefined color names, or with RGB, HEX, HSL, RGBA, or HSLA values.

  Color Names

  In HTML, a color can be specified by using a color name:

  Background Color

  You can set the background color for HTML elements:

  Lorem ipsum dolor sit amet, consectetuer adipiscing elit, sed diam nonummy nibh euismod tincidunt ut laoreet dolore magna aliquam erat volutpat. Ut wisi enim ad minim veniam, quis nostrud exerci tation ullamcorper suscipit lobortis nisl ut aliquip ex ea commodo consequat.

  Example

  Hello World

  Lorem ipsum.

  Text Color

  You can set the color of text:

  Hello World

  Lorem ipsum dolor sit amet, consectetuer adipiscing elit, sed diam nonummy nibh euismod tincidunt ut laoreet dolore magna aliquam erat volutpat.

  Ut wisi enim ad minim veniam, quis nostrud exerci tation ullamcorper suscipit lobortis nisl ut aliquip ex ea commodo consequat.

  Example

  Hello World

  Lorem ipsum.

  Ut wisi enim.

  Border Color

  You can set the color of borders:

  Hello World

  Hello World

  Hello World

  Example

  Hello World

  Hello World

  Hello World

  Color Values

  In HTML, colors can also be specified using RGB values, HEX values, HSL values, RGBA values, and HSLA values.

  The following three elements have their background color set with RGB, HEX, and HSL values:

  The following two elements have their background color set with RGBA and HSLA values, which add an Alpha channel to the color (here we have 50% transparency):
