Black and White Comic are great! To feel like black&white it's worst then colored doesn't make sense because they are good in different ways.
Different types of comic, with different styles and stories will stand out better in Black&White or in color it depends.
You need to think about what do you feel it's better to show you story!
Having color doesn't mean automatically it's a good comic! A comic has a lot of factors for making it great! Story, style, illustration and more!
You can start to make it black&white, if you feel in the future give a bit of color could emphasize some episode or moment try giving it a bit of color! But you don't need too !
Don't be afraid of trying new things!
BEST OF LUCK!!
