Are there constants for colors?

  Well, technically hex is also RGB, but I get what you mean.
  
  You can use some online converting tool to get hex value http://www.javascripter.net/faq/rgbtohex.htm
  
  of use some conversion functions http://gameon365.net/topic/1886-lua-convert-rgb-colors-to-hex/
  
  but usually, all design programs, like photoshop, paint.net, etc can already output the color in any desired format, including hex.

  I don't know of any, but there are a ton of online tools you can use.
  
  Here's a page with a color chart:
  http://html-color-codes.com/
  
  And here's a color picker which shows you the hex code at the top:

  I'm sure there are many others - I googled "hexadecimal color" to find those.

  You can do this...

  function rgbToColor(r, g, b)   local sum = r * 65536 + g * 256 + b   return sum   end   application:setBackgroundColor(rgbToColor(123, 321, 124))

  Alternatively you can also use this free mac utility (SIP)to pick colors from screen/images and convert to the format that you want (copied to your clipboard)
  
  Link : SIP
  
  It provides easy navigation between color models, color history...
  I found it to be useful in my workflow.
