Description

Representation of RGBA colors.

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 (r,g,b) define a color in RGB color space. Alpha component (a) defines transparency - alpha of one is completely opaque, alpha of zero is completely transparent.
Static Variables
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 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!
Variables
a Alpha component of the color.
b Blue component of the color.
g Green component of the color.
gamma A version of the color that has had the gamma curve applied.
grayscale The grayscale value of the color. (Read Only)
linear A version of the color that has had the inverse gamma curve applied.
r Red component of the color.
this[int] Access the r, g, b,a components using [0], [1], [2], [3] respectively.
Constructors
Color Constructs a new Color with given r,g,b,a components.
Functions
ToString Returns a nicely formatted string of this color.
Static Functions
Lerp Interpolates between colors a and b by t.
Operators
Color Colors can be implicitly converted to and from Vector4.
operator - Subtracts color b from color a. Each component is subtracted separately.
operator * Multiplies two colors together. Each component is multiplied separately.
operator / Divides color a by the float b. Each color component is scaled separately.
operator + Adds two colors together. Each component is added separately.
Vector4 Colors can be implicitly converted to and from Vector4.
