The alpha channel of a Color structure determines the amount of transparency the Color has. An alpha value of 1 indicates the Color is completely opaque and a value of 0 indicates the color is completely transparent.
The sRGB channels (, R, G, B) and the ScRGB channels (ScA, ScR, ScG, ScB) of the Color structure are synchronized properties. For example, when , the sRGB alpha channel, is modified, the ScRGB alpha channel, ScA, is transformed to the equivalent value.
