Functions

blend

fun blend(other: KutintColor<*>, amount: Float = 0.5f): RGB

Blends two colors together using a linear interpolation between them in the RGB color space.

complement

fun complement(): HSL

Gets the complementary color in the HSL color space.

darken

infix fun darken(amount: Float = 0.2f): HSL

Darkens the color, through the HSL color space, by a given amount.

desaturate

infix fun desaturate(amount: Float = 0.2f): HSL

Desaturates the color, through the HSL color space, by a given amount.

grayscale

fun grayscale(): RGB

Converts the color to grayscale using the W3C formula for relative luminance through the RGB color space.

hueRotate

infix fun hueRotate(degrees: Int = 30): HSL

Rotates the hue in the HSL color space by a given number of degrees.

invert

fun invert(): RGB

Inverts the color by subtracting each channel from 255 in the RGB color space.

infix fun tint(amount: Float = 0.2f): RGB

Tints the color, using a linear interpolation between the original color and white in the RGB color space, by a given amount.

toHex

fun toHex(includeAlpha: Boolean = alpha < 1f): String

Converts the color to a hex string.

toString

open override fun toString(): String

withAlpha

open infix override fun withAlpha(newAlpha: Float): RGB
