No, in most cases manually picked cp will be more accurate (when set 
correctly) - because a human will select more appropriate places - e.g. 
prefer non-moving objects.
(And in the time before cp finder like cpfind or autopano-sift it was the 
only way to add control points.)

The color is an indicator for the current cp error distance. After adding 
cp you need to re-optimize the project so that the new cp are taken into 
consideration for calculation of the positions. Then the color will 
change.
