So faded question

Hi everyone. I am an advanced beginner knitter working on my third ever sweater. It is the So faded by dreareneeknits. She talks about changing colours to fade at a raglan seam. I emailed her to ask for clarification and then she said at any of the raglan stitches. The thing is, I don’t know exactly what that means. The beginning of a row is the front of the neck, so if I change yarn close to the raglan seam (which is I believe the little design detail that goes from collar bone to underarm), it isn’t the beginning of the row, so won’t it look off centre? Am I even understanding this properly at all? This is more or less my first encounter with changing yarn colours so I am not sure how to proceed. Thank you in advance for any help you can provide.

Very nice looking sweater and good for you for venturing into sweaters.
Changing at a raglan seam is a good idea rather than in the center front. It’ll merge into the succeeding rows and won’t give an asymmetric look to the sweater.
Usually you work an increase before and after the raglan seam. After the first of these, drop the old color and continue to knit with the new color. Leave about a 6" tail in both cases to weave in later.
