Class ColorDatabase

java.lang.Object
  android.image.ColorDatabase

public class ColorDatabase
extends java.lang.Object

Manages color names and translation to implementation-dependent Color structures.

Available colors are listed in the following table. If an undefined color is used then a RuntimeException is thrown. Custom colors can be created using the static makeColor methods.

Alternatively clients can specify a 7 character string beginning with a '#' (hash-mark) followed by a 6 digit hexadecimal number that encodes the requested RGB color, e.g., "#FF0000" for Red, or "#00FF00" for Green. For advanced users, a 9 character string beginning with a '#' followed by an 8 digit hexadecimal number that encodes the requested ARGB color (Alpha, Red, Green, Blue), e.g., "#FFFF0000" for Opaque Red, or "#8800FF00" for Half-Transparent Green.

Color names are case-insensitive.
