Hey! In the documentation is briefly mentioned how to change atoms colors, by editing a text file as the one provided in the /data directory. The problem is that file is just a list of numbers of difficult comprehension, I have problems to associate them to any specific element. Could you provide me with a couple of brief examples on how to use this file to change elements colors in Molekel (e.g. to change Si color to yellow)? Also it could be nice as future features to have a simple menu way to do this (as it is already possible for the background), as well as for the surface/orbitals colors, in this aspect Molden 4.3 was superb! Thank you and Keep up the good work, Matteo

Hi, the sample file lists one atom color per line. The line number matches the atomic number e.g. 8th line -> atomic number 8. Colors are encoded as red, green and blue values between 0 and 1. To change the Si color simply go to line 14 and change the rgb values.

Great! Thank you!
