diverge-hsl clj

(diverge-hsl numcolors & opts)

Compute a set of colors diverging from a neutral center (grey or white, without color) to two different extreme colors (blue and red by default). For the diverging HSL colors, again two hues :h are needed, a maximal saturation ':s' and two lightnesses ':l'. The colors are then created by an interpolation between the full color hsl1, a neutral color hsl and the other full color hsl2.

Arguments: numcolors: Number of colors to be produced in this palette.

Optional Arguments: :h-start (keyword) starting hue (default 260) :h-end (keyword) ending hue (default 0) :s (keyword) saturation. 0.0 - 100.0 (default 80.0) :l-start (keyword) starting lightness. 0.0 - 100.0. (default 30.0) :l-end (keyword) ending lightness. 0.0 - 100.0. (default 90.0) :power (keyword) control parameter determining how saturation and lightness should be increased (1 = linear, 2 = quadratic, etc.) (default 1.5)

heat-hsl clj

(heat-hsl numcolors & opts)

Create heat palette in HSL space. By default, it goes from a red to a yellow hue, while simultaneously going to lighter colors (i.e., increasing lightness) and reducing the amount of color (i.e., decreasing saturation).

Arguments: numcolors: Number of colors to be produced in this palette.

Optional Arguments: :h-start (keyword) starting hue (default 260) :h-end (keyword) ending hue (default 260) :s-start (keyword) starting saturation. 0.0 - 100.0 (default 80.0) :l-start (keyword) starting lightness. 0.0 - 100.0. (default 30.0) :s-end (keyword) ending saturation. 0.0 - 100.0 (default 0.0) :l-end (keyword) ending lightness. 0.0 - 100.0. (default 90.0) :power-saturation (keyword) control parameter determining how saturation should increase :power-lightness (keyword) control parameter determining how lightness should increase be increased (1 = linear, 2 = quadratic, etc.)

inclusive-seq clj

(inclusive-seq n start end)

Return n evenly spaced points along the range start - end (inclusive).

rainbow-hsl clj

(rainbow-hsl numcolors & opts)

Computes a rainbow of colors (qualitative palette) defined by different hues given a single value of each saturation and lightness.

Arguments: numcolors: Number of colors to be produced in this palette.

Optional Arguments: :s (keyword) saturation. 0.0 - 100.0 (default 50.0) :l (keyword) lightness. 0.0 - 100.0. (default 70.0) :start (keyword) hue where rainbow starts. 0 - 360 (default 0) :end (keyword) hue where rainbow ends. 0 - 360 (default: (* 360 (/ (- numcolors 1) numcolors)))

sequential-hsl clj

(sequential-hsl numcolors & opts)

Creates a sequential palette starting at the full color (h :s-start :l-start) through to a light color (h :s-end :l-end) by interpolation.

Arguments: numcolors: Number of colors to be produced in this palette.

Optional Arguments: :h (keyword) starting hue (default 260) :s-start (keyword) starting saturation. 0.0 - 100.0 (default 80.0) :l-start (keyword) starting lightness. 0.0 - 100.0. (default 30.0) :s-end (keyword) ending saturation. 0.0 - 100.0 (default 0.0) :l-end (keyword) ending lightness. 0.0 - 100.0. (default 90.0) :power (keyword) control parameter determining how saturation and lightness should be increased (1 = linear, 2 = quadratic, etc.)

terrain-hsl clj

(terrain-hsl numcolors & opts)

The 'terrain_hcl' palette simply calls 'heat_hcl' with different parameters, providing suitable terrain colors.
