Adding a check for r and returning a value should fix that. Update the hex function to this.

Code:
local function hex(r, g, b)
  if(not r) then return "|cffFFFFFF" end

  if(type(r) == 'table') then
    if(r.r) then r, g, b = r.r, r.g, r.b else r, g, b = unpack(r) end
  end

  if(r > 1) then
    return ('|cff%02x%02x%02x'):format(r, g, b)
  else
    return ('|cff%02x%02x%02x'):format(r * 255, g * 255, b * 255)
  end
end
