text: user9824: Hello I am a Pymol user
  I want to color all alpha carbons (ca) and beta carbons (cb) from a certain ressidue in different color. How can I do this?
  I selected the spheres with:
  show spheres, C/1-9/ca 
  show spheres, C/1-9/cb
  
  
  and if I use
  set sphere_color, theColor
  
  I color all the spheres what I don't want.
  according to: color    gold,    resi    200-­‐221
  I tried
  gold,    spheres, C/1-9/ca
  but this didn't work

  So how PyMOL stores how it shows atoms is that each atom has a colour and a represention, which is a binary number telling what to show. Therefore the colour for spheres is the same as the colour for sticks. The only way round this is to copy the object (create copycat, original and you set copycat differently)
  To set the atom you do
  select iliketheschaps, resi 200‐221 and name CA+CB
  color tv_green, iliketheschaps
  show spheres, iliketheschaps
  
  The object iliketheschaps is a selection. Do make sure the range is a hyphen-minus (character next to 0) as opposed to an en-dash (–) which Word subs and on a mac you get with cmd+-
  non-PyMOL colours
  Now you asked for "gold". This is not a colour in the menu —famous for the colour limon. Gold is a CSS colour name, but it won't work.
  You will have to colour by hex code. Say you want "gold" you need to google the colour name and hex. #FFD700.
  color 0xFFD700, iliketheschaps

  This paragraph is in jest.
  
  However, as you may know bioinformaticians are very fashion savvy for colours. Mustard was the in-colour from last year, so you really ought to use mustard (0xffdb58). This year is all about nectarine (0xffa168) (which is not salmon —this ain't 2015!). Coral (0xff7f50) and teal (0x008080) were from previous years and are still are going strong!
