115 C<SDL::Color> is a wrapper for display format independent color
116 representations, with the same interface as L<SDL::Color>.
118 =head2 new ( -color => )
120 C<SDL::Color::new> with a C<-color> option will construct a new object
121 referencing the passed SDL_Color*.
123 =head2 new (-r => , -g => , -b => )
125 C<SDL::Color::new> with C<-r,-g,-b> options will construct both a SDL_Color
126 structure, and the associated object with the specified vales.
128 =head2 new (-pixel =>, -surface =>)
130 C<SDL::Color::new> with C<-pixel,-surface> options will generate a SDL_Color*
131 with the r,g,b values associated with the integer value passed by C<-pixel>
132 for the given C<-surface>'s format.
134 =head2 r ( [ red ] ), g( [ green ] ), b( [ blue ] )
136 C<SDL::Color::r, SDL::Color::g, SDL::Color::b> are accessor methods for
137 the red, green, and blue components respectively. The color value can be set
138 by passing a byte value (0-255) to each function.
140 =head2 pixel ( surface )
142 C<SDL::Color::pixel> takes a C<SDL::Surface> object and r,g,b values, and
143 returns the integer representation of the closest color for the given surface.
