Functions

color2hue(num colorValue, num shading, num tint) → num

returns a color saturation

complimentHex(num n, String hex) → List<String>

returns an length n array of hex strings. The 0th color is the same as the input hexString, while the others are colours corresponding to an eve turn around the colour wheel. If n is 3 for example, the two other colours would represent a 1/3 and 2/3 rotation of the colour wheel.

complimentHsl(num n, List<num> color) → List<List<num>>

returns an length n array of hsl Vector3. The 0th color is the same as the input hsl, while the others are colours corresponding to an eve turn around the colour wheel. If n is 3 for example, the two other colours would represent a 1/3 and 2/3 rotation of the colour wheel.

complimentRgb(num n, List<num> color) → List<List<num>>

returns an length n array of rgb Vector3. The 0th color is the same as the input rgb, while the others are colours corresponding to an eve turn around the colour wheel. If n is 3 for example, the two other colours would represent a 1/3 and 2/3 rotation of the colour wheel.

darkenHex(num amount, String hex) → String

returns a darkened hex string. amount is a value in the range [0, 1]

darkenHsl(num amount, List<num> color) → List<num>

returns a darkened hsl array. amount is a value in the range [0, 1]

darkenRgb(num amount, List<num> rgb) → List<num>

returns a darkened rgb array. amount is a value in the range [0, 1]

gradient(Function ease, int n, List<num> color1, List<num> color2) → List<List<num>>

returns an length n array of Vector3 colours. colours are between color1 and color2, and are spaced according to the easing function easeFn.

hex2hsl(String hex) → List<num>

returns a hex string

hex2rgb(String hex) → List<num>

returns a rgb array

hsl2css(num alpha, List<num> hsl) → String

returns an hsl css string like hsl(222, 50%, 75%, 0.6) from the hsl color and alpha value

hsl2hex(List<num> color) → String

returns a hex string

hsl2rgb(List<num> color) → List<num>

returns a rgb array

lerp3(num t, List<num> color1, List<num> color2) → List<num>

returns a Vector3 colour somewhere between c1 and c2. t is the "time" value in the range [0, 1]

lightenHex(num amount, String hex) → String

returns a lightened hex string. amount is a value in the range [0, 1]

lightenHsl(num amount, List<num> color) → List<num>

returns a lightened hsl array. amount is a value in the range [0, 1]

lightenRgb(num amount, List<num> rgb) → List<num>

returns a lightened rgb array. amount is a value in the range [0, 1]

linearGradient(num n, List<num> color1, List<num> color2) → List<List<num>>

returns an length n array of Vector3 colours. colours are evenly spaced between color1 and color2.

multiGradient(num n, List<List<num>> colors) → List<List<num>>

returns a length n array of Vector3 colours. colours are the ones formed from the linearGradient(n/(numColours-1), color1, color2) for all colours color1, color2, ..., colorN

rgb2css(num alpha, List<num> color) → String

returns an rgba css string like rgba(255, 255, 255, 1) from the rgb color and alpha value

rgb2hex(List<num> rgb) → String

returns a hex string

rgb2hsl(List<num> color) → List<num>

returns a hsl array

rGradient(Function ease, num n, List<num> color1, List<num> color2) → List<List<num>>

returns a rounded, length n array of Vector3 colours. colours are between color1 and color2, and are spaced according to the easing function easeFn.

rLinearGradient(num n, List<num> color1, List<num> color2) → List<List<num>>

returns a rounded, length n array of Vector3 colours. colours are evenly spaced between color1 and color2.

rMultiGradient(num n, List<List<num>> colors) → List<List<num>>

returns a rounded, length n array of Vector3 colours. colours are the ones formed from the linearGradient(n/(numColours-1), color1, color2) for all colours color1, color2, ..., colorN
