public struct Color : IEquatable<Color>, 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,Color.g,Color.b) define a color in RGB color space. Alpha component (Color.a) defines transparency - alpha of one is completely opaque, alpha of zero is completely transparent.
Fields
Value | Description |
|---|---|
| a | Alpha component of the color (0 is transparent, 1 is opaque). |
| b | Blue component of the color. |
| g | Green component of the color. |
| r | Red component of the color. |
Constructors
Constructor | Description |
|---|---|
| Color(System.Single,System.Single,System.Single) | Constructs a new Color with given r,g,b components and sets a to 1. |
| Color(System.Single,System.Single,System.Single,System.Single) | Constructs a new Color with given r,g,b,a components. |
Properties
Property | Description |
|---|---|
| gamma | A version of the color that has had the gamma curve applied. |
| grayscale | The grayscale value of the color. (Read Only) |
| this[] | Access the r, g, b,a components using [0], [1], [2], [3] respectively. |
| linear | A linear value of an sRGB color. |
| maxColorComponent | Returns the maximum color component value: Max(r,g,b). |
Static Properties
Property | Description |
|---|---|
| black | Solid black. RGBA is (0, 0, 0, 1). |
| blue | Solid blue. RGBA is (0, 0, 1, 1). |
| clear | Completely transparent. RGBA is (0, 0, 0, 0). |
| cyan | Cyan. RGBA is (0, 1, 1, 1). |
| gray | Gray. RGBA is (0.5, 0.5, 0.5, 1). |
| green | Solid green. RGBA is (0, 1, 0, 1). |
| grey | English spelling for Color.gray. RGBA is the same (0.5, 0.5, 0.5, 1). |
| magenta | Magenta. RGBA is (1, 0, 1, 1). |
| red | Solid red. RGBA is (1, 0, 0, 1). |
| white | Solid white. RGBA is (1, 1, 1, 1). |
| yellow | Yellow. RGBA is (1, 0.92, 0.016, 1), but the color is nice to look at! |
Methods
Method | Description |
|---|---|
| ToString | Returns a formatted string of this color. |
Static Methods
Method | Description |
|---|---|
| HSVToRGB | Creates an RGB colour from HSV input. |
| Lerp | Linearly interpolates between colors a and b by t. |
| LerpUnclamped | Linearly interpolates between colors a and b by t. |
| RGBToHSV | Calculates the hue, saturation and value of an RGB input color. |
Operators
Operator | Description |
|---|---|
| operator + | Adds two colors together. Each component is added separately. |
| operator / | Divides color a by the float b. Each color component is scaled separately. |
| Vector4 | Colors can be implicitly converted to and from Vector4. |
| Color | Colors can be implicitly converted to and from Vector4. |
| operator * | Multiplies color a by the float b. Each color component is scaled separately. |
| operator - | Subtracts color b from color a. Each component is subtracted separately. |
