Increases or decreases one or more channels of $color
by fixed amounts.
Adds the value passed for each keyword argument to the corresponding channel
of the color, and returns the adjusted color. By default, this can only adjust
channels in $color
’s space, but a different color space can be passed as
$space
to adjust channels there instead. This always returns a color in the
same space as $color
.
⚠️ Heads up!
For historical reasons, if $color
is in a legacy color space, any
legacy color space channels can be adjusted. However, it’s an error to
specify an RGB channel ($red
, $green
, and/or $blue
) at the same time
as an HSL channel ($hue
, $saturation
, and/or $lightness
), or either of
those at the same time as an HWB channel ($hue
, $whiteness
, and/or
$blackness
).
Even so, it’s a good idea to pass $space
explicitly even for legacy colors.
All channel arguments must be numbers, and must be units that could be passed for those channels in the color space’s constructor. If the existing channel value plus the adjustment value is outside the channel’s native range, it’s clamped for:
- red, green, and blue channels for the
rgb
space; - lightness channel for the
lab
,lch
,oklab
, andoklch
spaces; - the lower bound of the saturation and chroma channels for the
hsl
,lch
, andoklch
spaces; - and the alpha channel for all spaces.

Returns the value of $channel

, which defaults to $color

must be a quoted string, and the $space
must be an
unquoted string.
This returns a number with unit deg

If $color

Returns a color that’s a mixture of $color1

using $method
,
which is the name of a color space, optionally followed by a hue
interpolation method if it’s a polar color space (hsl
, hwb
, lch
, or
oklch
).
This uses the same algorithm to mix colors as the CSS color-mix()
function. This also means that if either color has a missing channel in the
interpolation space, it will take on the corresponding channel value from the
other color. This always returns a color in $color1
’s space.
The $weight
must be a number between 0%
and 100%
(inclusive). A larger
weight indicates that more of $color1
should be used, and a smaller weight
indicates that more of $color2
should be used.
⚠️ Heads up!
For historical reasons, $method
is optional if $color1
and $color2
are
both in legacy color spaces. In this case, color mixing is done using the
same algorithm that Sass used historically, in which both the $weight
and
the relative opacity of each color determines how much of each color is in
the result.

Fluidly scales one or more properties of $color

Each keyword argument must be a number between -100%
and 100%
(inclusive).
This indicates how far the corresponding property should be moved from its
original position towards the maximum (if the argument is positive) or the
minimum (if the argument is negative). This means that, for example,
$lightness: 50%
will make all colors 50%
closer to maximum lightness
without making them fully white. By default, this can only scale colors in
$color

to
scale channels there instead. This always returns a color in the same space as
$color
.
⚠️ Heads up!
For historical reasons, if $color
is in a legacy color space, any
legacy color space channels can be scaled. However, it’s an error to specify
an RGB channel ($red

The $method
indicates how Sass should choose a "similar" color:
-
local-minde
: This is the method currently recommended by the CSS Colors 4 specification. It binary searches the Oklch chroma space of the color until it finds a color whose clipped-to-gamut value is as close as possible to the reduced-chroma variant. -
clip

’s gamut, setting them to the minimum or maximum gamut values if they’re out-of-gamut.
⚠️ Heads up!
The CSS working group and browser vendors are still actively discussing
alternative options for a recommended gamut-mapping algorithm. Until they
settle on a recommendation, the $method
parameter is mandatory in
color.to-gamut()
so that we can eventually make its default value the same
as the CSS default.

- Dart Sass

- ✗
Converts $color
into the given $space
, which must be an unquoted string.
If the gamut of $color
’s original space is wider than $space
’s gamut, this
may return a color that’s out-of-gamut for the $space
. You can convert it to
a similar in-gamut color using color.to-gamut()
.
This can produce colors with missing channels, either if $color
has an
analogous channel that’s missing, or if the channel is powerless in the
destination space. In order to ensure that converting to legacy color spaces
always produces a color that’s compatible with older browsers, if $space
is
legacy this will never return a new missing channel.
💡 Fun fact:
This is the only Sass function that returns a color in a different space than the one passed in.

adjust-hue($color, $degrees) //=> color
Increases or decreases $color
’s HSL hue.
The $hue
must be a number between -360deg
and 360deg

must be in a legacy color space.

color.whiteness($color) //=> number

Returns the HWB whiteness of $color
as a number between 0%
and 100%
.
The $color
must be in a legacy color space.
⚠️ Heads up!
Because color.whiteness()
is redundant with color.channel()
,
it’s no longer recommended. Instead of color.whiteness($color)
, you can
write color.channel($color, "whiteness")
.
