This software assigns RGB values to popular color names.
For instance, you can use Graphics::ColorNames 2.10; use GD; $pal = new Graphics::ColorNames; $img = new GD::Image(100, 100); $bgColor = $img->colorAllocate($pal->rgb('CadetBlue3')); Even though this code may seem a little bureaucratic, its meaning is transparent - $bgColor (or background color) is 'CadetBlue3' (which is more comfortable for a user to understand than 0x7A, 0xC5, 0xCD). Moreover, the variable is named primarily for its function, not form (i.e., $CadetBlue3) to prevent the variable name from being changed later when the author changes the background color.
Additionally, you can define "Custom Color Schemes" for specialized palettes for websites or institutional publications: $color = $pal->hex('MenuBackground');. As an added feature, a hexadecimal RGB value in the form of #RRGGBB, 0xRRGGBB, or RRGGBB will return itself: $color = $pal->hex('#123abc'); # returns '123abc'.
The SYNOPSIS section of the documentation provides an example of how the module can be employed; thus, the application process becomes straightforward. With the aid of the SYNOPSIS, one can use the module with ease to capture required information like $po = new Graphics::ColorNames(qw( X )); $rgb = $po->hex('green'); # returns '00ff00' $rgb = $po->hex('green', '0x'); # returns '0x00ff00' $rgb = $po->hex('green', '#'); # returns '#00ff00' $rgb = $po->rgb('green'); # returns '0,255,0' @rgb = $po->rgb('green'); # returns (0, 255, 0) $rgb = $po->green; # same as $po->hex('green'); tie %ph, 'Graphics::ColorNames', (qw( X )); and $rgb = $ph{green}; # same as $po->hex('green');.
In conclusion, Graphics::ColorNames is a useful module that both beginners and expert developers can benefit from as it offers users a rich and convenient interface that provides simplified color naming conventions. When you plan to design any graphical user interface, using this module would be another step towards giving your users a streamlined and user-friendly experience.
