Creates a new colour with the specified levels of red, green, blue, and alpha (opacity). Arguments are clamped, if necessary, to the 0 to 1 range.
The amount of red light, from 0 to 1.
The amount of green light, from 0 to 1.
The amount of blue light, from 0 to 1.
The opacity of the colour, from 0 to 1.
The alpha value (opacity) of this colour, from 0 (transparent) to 1 (opaque) inclusive.
The amount of blue in this colour, from 0 (none) to 1 (maximum) inclusive.
The amount of green in this colour, from 0 (none) to 1 (maximum) inclusive.
The amount of red in this colour, from 0 (none) to 1 (maximum) inclusive.
Returns a new Color instance whose color is derived from this color by rotating its hue and multiplying its saturation, value, and alpha by the specified factors. This Color will be converted to HSV, adjusted by the specified factors, clamped to valid values, and then returned as a new Color.
The amount to rotate the hue by, measured in rotations. Use 0 for no change, 0.5 to use the opposite hue.
The saturation adjustment factor, from 0 to 1. Use 1 for no change, 0 to convert to greyscale.
The value adjustment factor. Use 1 to retain the current brightness.
The opacity of the colour, from 0 to 1. Use 1 for no change.
A Color instance representing the same color.
Mixes this color with another color as if by painting the specified top color over this color. If the top color is opaque, it will replace this color. Otherwise the colors will be blended in proportion to the top color's alpha value.
The color to mix in by “painting over” this color.
If specified, this value becomes the alpha value of the new color; otherwise the alpha value of the new color is the same as this color (the bottom color).
A new color that simulates layering the specified color over this color.
Mixes this color with another color, returning the new, combined color. The alpha values of the two input colors are ignored. The result will have red, green, and blue values at the midpoints between the two colors and an alpha of 1 (fully opaque).
The color to mix this color with.
An opaque color halfway between this color and the specified color.
Returns the value of the color as a 32-bit unsigned integer.
The color in RGBA32 format.
Returns a string representation of this colour using CSS hexadecimal notation. For example, a colour with red 1, green 0.75, blue 0.5, and opacity 0.25 might return the string "#ffbf8040".
A CSS hexadecimal string that describes this color.
Returns the value of the color in the HSV (hue-saturation-value) color space as an array in hue, saturation, value order.
Returns a string representation of this colour using CSS rgb() or rgba() notation. For example, a colour with red 1, green 0.75, blue 0.5, and alpha 0.25 might return the string "rgba(255,191,128,0.25)".
An rgb(a) string that describes this color.
Returns a new color identical to this color but with a different translucency (alpha value).
The new alpha value. The default is 1 (fully opaque).
A color identical to this color except that its alpha value is as specified.
Creates a Color instance from the specified 32-bit unsigned integer.
The color in RGBA32 format.
A Color instance representing the same color.
Creates a Color instance from the given byte values. If alpha is not specified, it is treated as 255 (fully opaque).
The amount of red light, from 0 to 255.
The amount of green light, from 0 to 255.
The amount of blue light, from 0 to 255.
The opacity of the colour, from 0 to 255.
A Color instance representing the described colour.
Creates a Color instance from the specified CSS Color value. Any notation recognized by the browser is acceptable, including functional (e.g., "rgba(176, 224, 230, 0.87)", "hsl(270deg, 60%, 70%)""), hexadecimal (e.g., "#b0e0e6"), and keywords (e.g., "powderblue"). As with theme colours, "hexa" notation (#rrggbbaa and #rgba) is allowed even when not supported by the browser. If the specified string is not a valid colour, null is returned instead.
A (possible) CSS Color value.
A Color instance representing the same color, or null if the string was not a valid.
Creates a Color instance from the given values in the HSV (hue-saturation-value) color space. If alpha is not specified, it is treated as 1 (fully opaque).
The hue, as an angle measured in rotations.
The saturation, from 0 to 1.
The value (roughly, the admixture of black or white), from 0 to 1.
The opacity of the colour, from 0 to 1.
A Color instance representing the same color.
Converts a colour value from the HSV (hue-saturation-value) color space to the RGB (red-green-blue) color space. The saturation and value arguments will be clamped, if necessary, to the 0 to 1 range. The hue value can be any number. The whole part is discarded and the fraction bits are used to describe an angle around a color wheel. (Multiply the hue by 360 to convert to degrees.)
The hue, as an angle measured in rotations.
The saturation, from 0 to 1.
The value (roughly, the admixture of black or white), from 0 to 1.
An array of the converted color components in red, green, blue order.
Converts a colour value from the RGB (red-green-blue) color space to the HSV (hue-saturation-value) color space. The arguments will be clamped, if necessary, to the 0 to 1 range.
The amount of red light, from 0 to 1.
The amount of green light, from 0 to 1.
The amount of blue light, from 0 to 1.
An array of the converted color components in hue, saturation, value order.
Converts an RGB or RGBA color description to a string in CSS rgb() or rgba() notation.
The amount of red light, from 0 to 1.
The amount of green light, from 0 to 1.
The amount of blue light, from 0 to 1.
The opacity of the colour, from 0 to 1.
A CSS rgb(a) string that describes the color.
Converts an RGB or RGBA color description to a string in CSS hexadecimal notation.
The amount of red light, from 0 to 1.
The amount of green light, from 0 to 1.
The amount of blue light, from 0 to 1.
The opacity of the colour, from 0 to 1.

An immutable representation of a colour in the sRGB (Standard Red Green Blue) space.
Each component of a Color is described by a number between 0 and 1 inclusive. For example, (0.5, 0, 0) would yield pure red at half the possible brightness. An alpha (opacity) level can optionally be specified as a fourth component, with 0 meaning fully transparent and 1 meaning fully opaque.
Color instances are immutable: once created, the component values of a particular Color can't be changed.
Example: Convert a CSS color name to its hex notation equivalent
