I'm guessing it's set up this way rather than a "default" color setting to allow maximum customization and freedom in the usage of the command. For instance, you can use multiple colors in the same statement or not use any colors at all. I don't know what it is you want to say, or in what colors, but chat binds are your friend.
This is all you really need:
bind p "dsay {crimson}°͜{red}ʖ{gold}°{lime}°͜{blue}ʖ{azure}°{indigo}°͜{purple}ʖ{crimson}°{red}°͜{gold}ʖ{lime}°{blue}°͜{azure}ʖ{indigo}°{purple}°͜{crimson}ʖ{red}°{gold}°͜{lime}ʖ{blue}°"
