Struct Color

Namespace: Terminal.Gui.Drawing

Assembly: Terminal.Gui.dll

Represents a 24-bit color encoded in ARGB32 format.

The RGB components define the color identity (what color it is), while the alpha channel defines rendering intent (how transparent it should be when drawn).

[JsonConverter(typeof(ColorJsonConverter))]
public readonly struct Color : ISpanParsable<Color>, IParsable<Color>, IUtf8SpanParsable<Color>, ISpanFormattable, IFormattable, IUtf8SpanFormattable, IMinMaxValue<Color>, IEquatable<Color>

Implements: ISpanParsable<Color>

IParsable<Color>

IUtf8SpanParsable<Color>

ISpanFormattable

IFormattable

IUtf8SpanFormattable

IMinMaxValue<Color>

IEquatable<Color>

Inherited Members: object.GetType()

object.Equals(object, object)

object.ReferenceEquals(object, object)

Remarks

When matching colors to standard color names (e.g., via GetColorName(Color)), the alpha channel is ignored. This means colors with the same RGB values but different alpha values will resolve to the same color name. This design supports transparency features while maintaining semantic color identity.

While Terminal.Gui does not currently support alpha blending during rendering, the alpha channel is used to indicate rendering intent:

Alpha = 0: Fully transparent (don't render)
Alpha = 255: Fully opaque (normal rendering)
Other values: Reserved for future alpha blending support

Constructors

Color(): Initializes a new instance of the Color with all channels set to 0.

Color(int): Initializes a new instance of the Color class with an encoded signed 32-bit color value in ARGB32 format.

Color(int, int, int, int): Initializes a new instance of the Color struct using the supplied component values.

Color(string): Initializes a new instance of the Color color from string. See TryParse(string, out Color?) for details.

Color(uint): Initializes a new instance of the Color class with an encoded unsigned 32-bit color value in ARGB32 format.

Color(in ColorName16): Initializes a new instance of the Color color from a legacy 16-color named value.

Color(in StandardColor): Initializes a new instance of the Color color from a value in the StandardColor enum.

Properties

Colors16: Gets or sets the 3-byte/6-character hexadecimal value for each of the legacy 16-color values.

Methods

Equals(object)

Equals(Color)

GetAnsiColorCode(): Gets the Color using a legacy 16-color ColorName16 value. get will return the closest 16 color match to the true color when no exact value is found.

GetBrighterColor(double): Returns a color with the same hue and saturation as this color, but with a significantly different lightness, making it suitable for use as a highlight or contrast color in UI elements.

GetClosestNamedColor16(): Gets the Color using a legacy 16-color ColorName16 value. get will return the closest 16 color match to the true color when no exact value is found.

GetDimColor(double): Returns a color with the same hue and saturation as this color, but with a significantly lower lightness, making it suitable for use as a shadow or background contrast color in UI elements.

GetHashCode()

IsClosestToNamedColor16(in ColorName16): Determines if the closest named Color to this is the provided namedColor.

ToString(): Converts the color to a string representation.

ToString(string?, IFormatProvider?): Returns a string representation of the current Color value, according to the provided formatString and optional formatProvider.

TryFormat(Span<byte>, out int, ReadOnlySpan<char>, IFormatProvider?)

TryFormat(Span<char>, out int, ReadOnlySpan<char>, IFormatProvider?)

TryParse(string, out Color?): Converts the provided string to a new Color instance.

Operators

implicit operator Color(uint): Implicit conversion from uint to Color, via the Color(uint) costructor.

implicit operator int(Color): Implicit conversion from Color to int by returning the value of the Rgba field.

implicit operator Vector4(Color): Implicit conversion to Vector3, where X = R, Y = G, and Z = B.

implicit operator uint(Color): Implicit conversion from Color to uint by returning the value of the Argb field.

implicit operator Color(ColorName16): Implicit conversion from Terminal.Gui.Drawing.Color.GetClosestNamedColor16(Terminal.Gui.Drawing.Color) to Color via lookup from Terminal.Gui.Drawing.ColorExtensions.ColorName16ToColorMap.
