How do you change the color of a trendline in a scatter plot?

[#1]

I'm trying to change the color of my scatter plot's trendline (attached a picture) from a teal color to just black. Is there a way to do this? Thank you!

[#2]

as Massimo Grossi said, change the second color as black. it worked for me..!!

Actually, I found out that changing the 9th color changed the color of my trendline. I have no idea as to why it corresponds with the 9th color, but my problem is solved for now. Thanks everyone.

perhaps the rule is:

look at the color  of the trendline

go to tab color

change the same color as the trendline to black (in your case)
