You just have to practice a little bit to get used to "WYSIWYG." And learn how that will drastically change things compared to b/w, with which we become so accustomed to "translating" everything in our heads that it becomes more natural to us than WYSIWYG. (Just like looking at negative feels completely natural to us once we have printed a little bit, but "difficult" at first.) With color, there is no grayscale to hide behind. It is much more difficult because it requires much more attention to detail, IMHO. Many subjects that don't naturally lend themselves to color require a different approach than you would take with b/w. You might find that different compositions or technical considerations work better, for instance, moving in closer to an object, or using less depth of field for a certain subject than you would with b/w. But all it takes is practice. And if you print your own film, you will learn all the quicker.
