tornado.colors — org.clojars.jansuran03/tornado 0.2.10

Everything related to colors: Mixing, color function such as rgb(a), hsl(a), color conversions, a map of available default colors, special function for modifying colors.

->hsl clj/s

(->hsl {:keys [type] :as color})

Converts a color to hsl.

->hsl?a clj/s

(->hsl?a color)

Converts a color to hsl/hsla, depending on whether the current form has an alpha value.

->hsla clj/s

(->hsla {:keys [type] :as color})

Converts a color to hsla.

->rgb clj/s

(->rgb {:keys [type] :as color})

Converts a color to rgb.

->rgba clj/s

(->rgba {:keys [type] :as color})

Converts a color to rgba.

-mix-colors clj/s multimethod

(-mix-colors color-type colors)

Calls a relevant function to compute the average of more colors. Presumes that the colors are converted to the same type by a function 'mix-colors'

alpha-hex? clj/s

(alpha-hex? x)

color clj/s

(color type value)

color->1-word clj/s

(color->1-word color)

Assumes that clojure.core/name can be cast to the argument. Transforms all 3 versions (string, symbol, keyword) to a keyword with removed dashes (e.g. 'dark-red -> :darkred).

color? clj/s

(color? x)

CSS-Color clj/s

darken clj/s

(darken color value)

Same as (lighten color value), but the value is subtracted instead.

default-colors clj/s

Available default colors in tornado. Usage: {:color :black :background-color :crimson :border [[(u/px 1) :solid :yellow-green]]} etc. Tornado does the hex-code translation for you. Also, you can use both e.g. :yellow-green and :yellowgreen (or in string and symbol-forms, respectively), it all compiles to the same color.

desaturate clj/s

(desaturate color value)

Same as (saturate color value), but the value is subtracted instead.

get-color-type clj/s

(get-color-type color)

Returns the type of the given color, either :type of a CSSColor record or the argument's class. If the class cannot represent a CSS color, throws an exception.

has-alpha? clj/s

(has-alpha? color)

Returns true if the color has an alpha parameter.

hex->rgba clj/s

(hex->rgba color)

(hex->rgba color alpha)

Converts a color in hexadecimal string to an rgba color:

(hex->rgba "#20FF3f") => #tornado.types.CSSColor{:type "rgba", :value {:red 32 :green 255, :blue 63 :alpha 1}}

(hex->rgba "#20FF3f" 0.3) => #tornado.types.CSSColor{:type "rgba", :value {:red 32 :green 255, :blue 63 :alpha 0.3}}

(hex->rgba "#20FF3f3f") => #tornado.types.CSSColor{:type "rgba", :value {:red 32 :green 255 :blue 63 :alpha 0.24609375}}

(hex->rgba "#20FF3f" "20 %") => #tornado.types.CSSColor{:type "rgba", :value {:red 32 :green 255 :blue 63 :alpha 0.2}}

As you can see, this conversion is not case-sensitive. Do not use tornado.units/percent as the second argument!

hex? clj/s

(hex? x)

hsl clj/s

(hsl [hue saturation lightness])

(hsl hue saturation lightness)

Creates an hsl CSSColor record.

hsl->hsla clj/s

(hsl->hsla {:keys [value]})

Hsl with alpha 1.

hsl->rgb clj/s

(hsl->rgb {:keys [value] :as hsl-color})

https://www.rapidtables.com/convert/color/hsl-to-rgb.html Hsl -> rgb, hsla -> rgba.

hsl? clj/s

(hsl? x)

hsla clj/s

(hsla [hue saturation lightness alpha])

(hsla hue saturation lightness)

(hsla hue saturation lightness alpha)

Creates an hsla CSSColor record.

hsla? clj/s

(hsla? x)

lighten clj/s

(lighten color value)

Lightens a color by a given value: 0.15, (percent 15), "15%" work the same way.

maybe-without-alpha clj/s

(maybe-without-alpha color)

If the color's alpha is 1, returns the same color without the alpha value.

mix-colors clj/s

(mix-colors color)

(mix-colors color1 & more)

Given any number of colors in any form (alpha-hex, non-alpha-hex, rgb, rgba, hsl, hsla), converts them to the most frequent type and mixes them.

named-color? clj/s

(named-color? x)

Returns true if the given color is in the name form and if it is contained in the default colors (e.g. :crimson, "dark-orchid", 'chocolate).

non-alpha-hex? clj/s

(non-alpha-hex? x)

opacify clj/s

(opacify color value)

Opacifies a color by a given value: 0.15, (percent 15), "15%" work the same way.

opposite-hue clj/s

(opposite-hue color)

Rotates a color's hue by 180°.

rgb clj/s

(rgb [red green blue])

(rgb red green blue)

Creates an rgb CSSColor record.

rgb->hex clj/s

(rgb->hex {:keys [type value] :as color})

Converts an rgb/rgba CSSColor record to a hex-string. Rounds the hex-alpha of the color if the color is in rgba format.

rgb->hsl clj/s

(rgb->hsl {:keys [value] :as rgb-color})

https://www.rapidtables.com/convert/color/rgb-to-hsl.html Rgb to hsl, rgba to hsla.

rgb->rgba clj/s

(rgb->rgba {:keys [value]})

Rgb with alpha 1.

rgb? clj/s

(rgb? x)

rgba clj/s

(rgba [red green blue alpha])

(rgba red green blue)

(rgba red green blue alpha)

Creates an rgba CSSColor record.

rgba->rgb clj/s

(rgba->rgb {:keys [value]})

Used for converting rgba to rgb since #'hex->rgba always returns rgba. Sometimes we might want and rgb color from that.

rgba? clj/s

(rgba? x)

rotate-hue clj/s

(rotate-hue color angle)

Rotates hue of a color by a given angle in degrees for any color type, e.g. (rotate-hue "#00ff00" 90)

saturate clj/s

(saturate color value)

Saturates a color by a given value: 0.15, (percent 15), "15%" work the same way.

scale-alpha clj/s

(scale-alpha color value)

Multiplies a color's alpha by a given value.

scale-lightness clj/s

(scale-lightness color value)

Multiplies a color's lightness by a given value.

scale-saturation clj/s

(scale-saturation color value)

Multiplies a color's saturation by a given value.

transparentize clj/s

(transparentize color value)

Same as (opacify color value), but the value is subtracted instead.

triad-next clj/s

(triad-next color)

Rotates a color's hue by 120°.

triad-previous clj/s

with-alpha clj/s

(with-alpha color alpha)

Given a color, sets its alpha to a given value.

with-alpha-param clj/s

(with-alpha-param color)

Returns the color with alpha = 1 if it does not have an alpha value already. Hex or named color gets converted to rgba.

with-hue clj/s

(with-hue color hue)

Given a color, transforms it into HSL and sets its hue to a given value.

with-lightness clj/s

(with-lightness color lightness)

Given a color, transforms it into HSL and sets its saturation to a given value.

with-saturation clj/s

(with-saturation color saturation)

Given a color, transforms it into HSL and sets its saturation to a given value.
