clojure2d.color
Color functions.
This namespace contains color manipulation functions which can be divided into following groups:
- Color creators
- Channel manipulations
- Conversions
- Palettes / gradients
- Distances
Representation
Color can be represented by following types:
- fastmath
Vec4- this is core type representing 3 color channels and alpha (RGBA). Values aredoubletype from[0-255]range. color, gray creators returnsVec4representation. - fastmath
Vec3- 3 channels (RGB), assumingalphaset to value of255. - fastmath
Vec2- gray with alpha java.awt.Color- Java AWT representation. Creators are awt-color, awt-gray. Use to-awt-color to convert to this representation.keyword- one of the defined names (see named-colors-list)Integer- packed ARGB value. If value is less than0xff000000, alpha is set to0xff. Example:0xffaa01.String- CSS (#rgbor#rgba) or string containg hexadecimal representation (“ffaa01”)- any
seqable- list, vector containing 2-4 elements. Conversion is done by applying content to color function.
To create color from individual channel values use color function. To create gray for given intensity call gray.
By default color is treated as RGB with values from ranges [0.0-255.0] inclusive.
All funtions internally convert any color representation to Vec4 type using to-color function..
Color/ channel manipulations
You can access individual channels by calling on of the following:
- red or ch0 - to get first channel value.
- green or ch1 - to get second channel value.
- blue or ch2 - to get third channel value.
- alpha - to get alpha value.
- luma - to get luma or brightness (range from
0(black) to255(white)). - hue - to get hue value in degrees (range from 0 to 360). Hexagon projection.
- hue-polar - to get hue from polar transformation.
set-ch0, set-ch1, set-ch2 and set-alpha return new color with respective channel set to new value.
General set-channel and get-channel can work with any colorspace.
To make color darker/brighter use darken / lighten functions. Operations are done in Lab color space.
To change saturation call saturate / desaturate. Operations are done in LCH color space.
You can also modulate color (ie. multiply by given value).
Conversions
Color can be converted from RGB to other color space (and back). List of color spaces are listed under colorspaces-list variable. There are two types of conversions:
- raw - with names
to-XXXandfrom-XXXwhereXXXis color space name. Every color space has it’s own value range for each channel.(comp from-XXX to-XXX)acts almost as identity. - normalized - with names
to-XXX*andfrom-XXX*whereXXXis color space name.to-XXX*returns values normalized to[0-255]range.from-XXX*expects also channel values in range[0-255].
NOTE: there is no information which color space is used. It’s just a matter of your interpretation.
NOTE 2: be aware that converting function do not clamp any values to/from expected range.
Color space conversion functions are collected in two maps colorspaces for raw and colorspaces* for normalized functions. Keys are color space names as keyword and values are vectors with to- fn as first and from- fn as second element.
Palettes / gradients
Links
List of all defined colors and palettes:
Palette
Palette is just sequence of colors.
There are plenty of them predefined or can be generated:
- palette to access palette by keyword (from presets), by number (from colourlovers). Use palette to resample palette or convert gradient to palette.
- paletton-palette function to generate palette of type:
:monochromatic,:triad,:tetradwith complementary color for given hue and configuration. See also Paletton website for details.
Call palette without any parameters to get list of predefined gradients.
Gradient
Gradient is continuous functions which accepts value from [0-1] range and returns color. Call gradient to create one.
Call gradient without any parameters to obtain list of predefined gradients.
Use gradient to convert any palette to gradient or access predefined gradients by keyword.
Conversions
To convert palette to gradient call gradient function. You can set interpolation method and colorspace. To convert gradient to palette call palette function.
Call palette to resample palette to other number of colors. Internally input palette is converted to gradient and sampled back.
Use lerp, lerp+, mix, average, mixbox to mix two colors in different ways.
Distances
Several functions to calculate difference between colors, delta-E*-xxx etc.

(gradient)(gradient palette-or-gradient-name)(gradient palette-or-gradient-name options)Return gradient function.
Grandient function accepts value from 0 to 1 and returns interpolated color.
Parameters;
palette-or-gradient-name- name of the predefined gradient or palette (seq of colors).- (optional) additional parameters map:
:colorspace- operate in given color space. Default::RGB.:interpolation- interpolation name or interpolation function. Interpolation can be one of interpolators-1d-list or easings-list. When easings is used, only first two colors are interpolated. Default::linear-smile.:to?- turn on/off conversion to given color space. Default:true.:from?- turn on/off conversion from given color space. Default:true.:domain- interpolation domain as seq of values for each color.
When called without parameters random gradient is returned.
