| creates a color with rgb-value (0,0,0), i.e. black.
Color c ( int red, int green, int blue);
| creates a color with rgb-value (red,green,blue).

### Operations

bool | c == q | Test for equality: Two colors are equal, iff their rgb-values are equal.
bool | c != q | Test for inequality.
int | c.red () | returns the red component of c.
int | c.green () | returns the green component of c.
int | c.blue () | returns the blue component of c.
