RGB: red green blue composite colors (H)

• Build a color value from its primary components:
  • color = RGB( red, green, blue [, indx] )
• the option indx=24...31 sets the

  predefined_color

  (indx) to the red, green, blue values given, so that it can be used like the indices 0...23 ⇒ Colors.
• with the use of indx the color value defined by RGB is saved
  • indx ≤ 24 sets color(24)
  • indx ≥ 31 sets color(31)
• the actual representation of a color is dependent upon the Windows configuration where it is displayed.
• the maximum value for each argument is 255, e.g.:
  • black = RGB( 0, 0, 0)
  • red= RGB(255, 0, 0)
  • yellow=RGB(255, 255, 0)
  • white = RGB(255, 255, 255)
  • lightblue=RGB(166, 202, 240, 31) ! sets the predefined color 31 to lightblue
  • Both, lightblue or 31, can be used as options in HicEst function calls, e.g.:
    • WRITE(BaCkcolor=black, ForeColor=31) string ! write to screen
    • WRITE(BaCkcolor=black, ForeColor=lightblue) string ! same result
