list colors used in color scheme

[tim bradshaw]

Hi there

Anyone know if there is a way of listing the colors used in a color scheme, ordered by first, second, third preference, etc?

[tim bradshaw]

Or, to ask a slightly different question, how to find out the names of the line colors used in a line graph?

[Nick Cox]

I don't know a method better than to look for all lines in a scheme file starting with color.

In practice, many, I guess, most schemes are defined by overwriting some of the settings of s2color. So, you need when that is true to look at two scheme files at least.

Thanks Nick, for your reply.
That's a shame because sometimes you might like the look of a color but want to re-order it.

palettes from SSC can show you this. As Nick notes, the selection depends on your scheme.

ssc install palettes, replace
colorpalette, lc(black): s2 / s1 / s1r / economist / mono

I sometimes open up the Graph Editor to find which colour was used for a particular graph element.

I've just come across this thread whilst searching for similar info.
In case it's of interest to others, in Stata 18 you can now refer to scheme colours specifically, rather than just the overall style. That is: mcolor(stc1) means "give my marker the colour from within style p1". Put another way: stc1, ..., stc15 are now permissible colour names for twoway in the same way as "blue", "green", etc. This is documented under help colorstyle. I've found this really helpful when coding, because you can parse style-specific colour options without worrying about the styles themselves.

maybe:

* schemes white_ptol gg_hue from https://github.com/asjadnaqvi/stata-schemepack

foreach scheme in white_ptol gg_hue economist {
    
    set scheme `scheme'

    gr_setscheme

    forvalues i = 1/15 {
        
        local p`i' `.__SCHEME.color.p`i''

        di "`scheme' p`i': `p`i''"
    }
    
    di _n 
}
