Grease Pencil assign new color?

Hi, I apologize if this thread is in the wrong section.

I have created different grease pencil strokes on different layers. If I create a new Stroke/Fill color in the Palette (Npanel) how do I assign this new Stroke/Fill color to a specific grease pencil layer? Thanks in advance!

Just figured it out!
There’s a black down arrow>click “Move to Color”
YES

Shoot… it seems like this solution isn’t 100% consistent…
sometimes when I draw a grease pencil shape and it’s filled with a different color I can’t seem to switch the color.
Can anyone offer another solution?

Since no one answered my question - here is the answer which I discovered for myself
Grease Pencil has and “Edit mode” as well - it’s called Edit Strokes
use “L” to hover over and select the shape you want
Then in the N panel, use the down arrow and choose “Move to Color”
