Can a script change conditional settings? Building theme options

[Morenomdz]

Hello there, I am thinking on having two or three different themes on the main list layout of my solution, one of my operator likes more an specific set of colors for the background on the lines and alternate lines, the others like it on a whole different set of colors etc. The thing is that if I change that color I must change the conditional formating as well as the ones I have set are totaly dependent of the background color of the line.

So the questions, using script lines, can I change the background color of an layout object lets say the body of the layout? Can I set a script to change the conditional formating as well?

If yes, then I can have the same layout and make buttons or a value list to set different color themes, if not, I will just go ahead and make a whole new layout for each theme.

As always thank you very much for the help!
