Hi Barry, To change the label color use menu Actions / Color / All Options... and choose the Color Applies To "atom labels" option to color just the labels of the selected atoms. Then click on the color you want. To adjust the font size use menu entry Favorites / Preferences choose Category "Background", and you can adjust the Label font size there. All atom labels have to have the same size. There are also "2d" labels that aren't attached to the atoms under Tools / Utilities / 2D Labels and those can be independently sized and colored. But they don't move when you rotate your molecule. Can be useful for making presentation images though. Tom
Forgive me for asking an obvious (to you) question,,, when I label/other to place, for example, spin quantities on each atom- where can I change the font and color of these labels so that they are more easily read ?? Thanks
Barry
