# Chemfig: colored unshared electron pair

Can I color the unshared electron pair with Chemfig? With this

R'-[0]\textcolor{red}{\lewis{2:6:,O}}H


The oxygen becomes red, but his unshared electron pair remains in black

• You are more likely to get the answer you are looking for if you include more details. Usually a complete working version starting from \documentclass all the way down to \end{document} would help a lot! – caverac Mar 11 '18 at 15:30
