# Color > Representation of RGBA colors. ## Definition * **Type:** Struct * **Namespace:** [UnityEngine](/engine/6000.0/script-reference/unityengine.md) * **Assembly:** UnityEngine.CoreModule * **Implements:** [IEquatable\](https://learn.microsoft.com/dotnet/api/system.iequatable-1), [IFormattable](https://learn.microsoft.com/dotnet/api/system.iformattable) ```csharp public struct Color : IEquatable, IFormattable ``` ## Remarks This structure is used throughout Unity to pass colors around. Each color component is a floating point value with a range from 0 to 1. Components ([Color.r](/engine/6000.0/script-reference/unityengine/color/r.md),[Color.g](/engine/6000.0/script-reference/unityengine/color/g.md),[Color.b](/engine/6000.0/script-reference/unityengine/color/b.md)) define a color in RGB color space. Alpha component ([Color.a](/engine/6000.0/script-reference/unityengine/color/a.md)) defines transparency - alpha of one is completely opaque, alpha of zero is completely transparent. ## Fields | Value | Description | | ----------------------------------------------------------- | ------------------------------------------------------------- | | [a](/engine/6000.0/script-reference/unityengine/color/a.md) | Alpha component of the color (0 is transparent, 1 is opaque). | | [b](/engine/6000.0/script-reference/unityengine/color/b.md) | Blue component of the color. | | [g](/engine/6000.0/script-reference/unityengine/color/g.md) | Green component of the color. | | [r](/engine/6000.0/script-reference/unityengine/color/r.md) | Red component of the color. | ## Constructors | Constructor | Description | | ------------------------------------------------------------------------------------------------------------------------------------------------------------ | ------------------------------------------------------------------- | | [Color(System.Single,System.Single,System.Single)](/engine/6000.0/script-reference/unityengine/color/ctor.md#color\(float-float-float\)) | Constructs a new Color with given r,g,b components and sets a to 1. | | [Color(System.Single,System.Single,System.Single,System.Single)](/engine/6000.0/script-reference/unityengine/color/ctor.md#color\(float-float-float-float\)) | Constructs a new Color with given r,g,b,a components. | ## Properties | Property | Description | | ------------------------------------------------------------------------------------------- | -------------------------------------------------------------------------- | | [gamma](/engine/6000.0/script-reference/unityengine/color/gamma.md) | A version of the color that has had the gamma curve applied. | | [grayscale](/engine/6000.0/script-reference/unityengine/color/grayscale.md) | The grayscale value of the color. (Read Only) | | [this\[\]](/engine/6000.0/script-reference/unityengine/color/item.md) | Access the r, g, b,a components using \[0], \[1], \[2], \[3] respectively. | | [linear](/engine/6000.0/script-reference/unityengine/color/linear.md) | A linear value of an sRGB color. | | [maxColorComponent](/engine/6000.0/script-reference/unityengine/color/maxcolorcomponent.md) | Returns the maximum color component value: Max(r,g,b). | ## Static Properties | Property | Description | | ----------------------------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------- | | [black](/engine/6000.0/script-reference/unityengine/color/black.md) | Solid black. RGBA is (0, 0, 0, 1). | | [blue](/engine/6000.0/script-reference/unityengine/color/blue.md) | Solid blue. RGBA is (0, 0, 1, 1). | | [clear](/engine/6000.0/script-reference/unityengine/color/clear.md) | Completely transparent. RGBA is (0, 0, 0, 0). | | [cyan](/engine/6000.0/script-reference/unityengine/color/cyan.md) | Cyan. RGBA is (0, 1, 1, 1). | | [gray](/engine/6000.0/script-reference/unityengine/color/gray.md) | Gray. RGBA is (0.5, 0.5, 0.5, 1). | | [green](/engine/6000.0/script-reference/unityengine/color/green.md) | Solid green. RGBA is (0, 1, 0, 1). | | [grey](/engine/6000.0/script-reference/unityengine/color/grey.md) | English spelling for [Color.gray](/engine/6000.0/script-reference/unityengine/color/gray.md). RGBA is the same (0.5, 0.5, 0.5, 1). | | [magenta](/engine/6000.0/script-reference/unityengine/color/magenta.md) | Magenta. RGBA is (1, 0, 1, 1). | | [red](/engine/6000.0/script-reference/unityengine/color/red.md) | Solid red. RGBA is (1, 0, 0, 1). | | [white](/engine/6000.0/script-reference/unityengine/color/white.md) | Solid white. RGBA is (1, 1, 1, 1). | | [yellow](/engine/6000.0/script-reference/unityengine/color/yellow.md) | Yellow. RGBA is (1, 0.92, 0.016, 1), but the color is nice to look at! | ## Methods | Method | Description | | ------------------------------------------------------------------------- | ----------------------------------------- | | [ToString](/engine/6000.0/script-reference/unityengine/color/tostring.md) | Returns a formatted string of this color. | ## Static Methods | Method | Description | | ----------------------------------------------------------------------------------- | --------------------------------------------------------------- | | [HSVToRGB](/engine/6000.0/script-reference/unityengine/color/hsvtorgb.md) | Creates an RGB colour from HSV input. | | [Lerp](/engine/6000.0/script-reference/unityengine/color/lerp.md) | Linearly interpolates between colors a and b by t. | | [LerpUnclamped](/engine/6000.0/script-reference/unityengine/color/lerpunclamped.md) | Linearly interpolates between colors a and b by t. | | [RGBToHSV](/engine/6000.0/script-reference/unityengine/color/rgbtohsv.md) | Calculates the hue, saturation and value of an RGB input color. | ## Operators | Operator | Description | | --------------------------------------------------------------------------------- | ----------------------------------------------------------------------------------------------------------------- | | [operator +](/engine/6000.0/script-reference/unityengine/color/op-addition.md) | Adds two colors together.
