Chemfig and tikz: shaded arrow

Building upon Sebastiano's answer, one can also apply the path fading option directly to chemfig arrows as shown in the following example:



enter image description here



documentclass{article}

usepackage{chemfig}

usepackage[version=3]{mhchem}

usetikzlibrary{fadings}



begin{document}



begin{figure}[!htb]

centering

scalebox{2}{

schemestart

chemfig{@{O1-2}textcolor{gray}{O}=@{C1-2}textbf{C}=@{O2-2}textcolor{gray}{O}}

schemestop

chemmove{    

      draw[blue, path fading = west][shorten <=3pt, shorten >=3pt](O1-2).. controls +(north:1cm) and +(120:1cm).. (C1-2);  

      draw[blue, path fading = east][shorten <=3pt, shorten >=3pt](O2-2).. controls +(north:1cm) and +(60:1cm).. (C1-2);     

}

}

end{figure}

    A possible solution with tikz-cd it is very simple to have the arrows shades to blue from white.



    enter image description here



    documentclass[a4paper,12pt]{article}
    
usepackage{tikz-cd,amsmath}
    
usetikzlibrary{fadings}
    
begin{document}
    
begin{tikzcd}[column sep=.7cm]
    
color{gray}{mathrm{O}}
    
 arrow[r, equal, no head] arrow[r, bend left=49, blue, path fading=west] & mathbf{C} arrow[r, no head, equal] & color{gray}{mathrm{O}} arrow[l, bend right=49, blue, path fading=east]
    
end{tikzcd}
    
end{document}

      +1. Maybe you want to add, that path fading can also be applied to chemfig arrows. Using draw[blue, path fading = west][shorten <=3pt, shorten >=3pt](O1-2).. controls +(north:1cm) and +(120:1cm).. (C1-2); ... will result in the following output: i.stack.imgur.com/YMnc8.png

            ComboBox Display Member on multiple fields

            Is it possible to collect Nectar points via Trainline?

            Image
            2 Since I am not eligible for any Railcard, the only available discount/bonus scheme is Nectar Card for me. GWR, SWR, LNER and Virgin Trains allow to collect Nectar points and I have already linked a card to my GWR account.
