class Color [ java.awt ]

• An Object of this type represents a Color.
• This class provides us 12 ready made color objects.

• public static final Color red;
• public static final Color blue;
• public static final Color green;
• public static final Color yellow;
• public static final Color orange;
• public static final Color pink;
• public static final Color magenta;
• public static final Color cyan;
• public static final Color white;
• public static final Color black;
• public static final Color darkGray;
• public static final Color lightGray;

        g.setColor(Color.red);
        g.drawOval(10,20,200,100);

• Color(int r, int g, int b)
• Creates a color with specified RGB components.
• values are in range 0 – 255
for ex:
Color c=new Color(0,0,255);
g.setColor(c);
• Color(float r, float g, float b)
• creates a color with specified RGB components.
• values are in range 0.0 – 1.0
for ex:
Color c=new Color( 0.0f,0.0f,1.0f);
g.setColor(c);

• Color darker()
• Creates a new Color that is a darker version of this Color.
for ex:
Color c1=Color.red;
Color c2=c1.darker();
• Color brighter()
• Creates a new Color that is a brighter version of this Color.

RGB Color Modal

• It is used to create color object by using the RGB (Red, Green, Blue) color model.
Syntax:
Color c=new Color(red, green,blue)
• red : a value from 0 and 255 to indicate the amount of red.
• green : a value from 0 and 255 to indicate the amount of green.
• blue : a value from 0 and 255 to indicate the amount of blue.

HSB Color Modal

• It is used to create color object by using the HSB color model.

• Hue
• It is number between 0.0 and 1.0 which indicates the hue of the color.
• Saturation
• It is number between 0.0 and 1.0 which indicates color depth.
• 1 will make the color as deep as possible.
• 0 will take all the color out of the mixture and make it a shade of gray.
• Brightness
• Is is decimal number between 0.0 and 1.0 which indicates brightness.
• 1 will make the color as light as possible.
• 0 will make it very dark.
