Colour is in some ways easier then B&W. B&W isn't a normal state for most of us. So when we look at a B&W print it's open to much more creative interperation. OTOH with a colour print if the grass isn't green people will notice.
First you get the exposure right. Then you get the colour balance right. Always exposure first. Get a hair dryer to dry the test prints. You can't judge wet prints well. Worse when you start adjusting the colour you may need to adjust the exposure a little.
