Different blue color in twoway chart than the marginsplot

[Hossein Jebeli]

The marginsplot generates the following chart:

sysuse auto, clear
logistic foreign mpg price rep78
margins , at(rep78=(1(1)5))
marginsplot

However the blue color of the following plot is different:

collapse (mean) price , by(rep78)
twoway line price rep78 , lcolor(blue)

Is there a way to make the blue color in the twoway similar to the first one coming from Stata's default for marginsplot, so that I can present all my charts in the same blue color?

Stata uses a colour it terms stblue as the blue for the default stcolor scheme in Stata 18. You can see this mentioned in

help colorstyle

You can check what this colour is in terms of RGB by doing:

. palette color stblue
("stblue" = "26    133    255"%100)

The line colour in #1 (coming from Stata 18) is stc1.

Just a quick note to add that there is no conflict between #2 and #3. stc1 and stblue are synonymous.

. palette color stc1 stblue
("stc1" = "26    133    255"%100, "stblue" = "26    133    255"%100)
