Hi Elaine,

Thank you for the explanation. I currently have version 1.4.1 build 20308. I got it just a few weeks ago and didn't expect a newer version would be available. Great! 

Thanks for developing Chimera, its great and easy to use. Although this is not the right forum, if you don't mind I would like to make a suggestion. For the ribbons representation of nucleic acids, I have been using RIBBONS, its rendering is really pleasing. Chimera's rendering is close but it would be great if it possible to match that of ribbons.

Thanks again.

Best wishes,

If you are using Chimera 1.5 (daily builds), the Color Editor will do the conversion for you:  if you type in a value greater than 1 but no greater than 255 for a color component and press return, it will automatically be divided by 255:
