OK which also shows the current
selected colour. If you have set a colour with the background or
foreground option in the viewmolrc file, the rightmost coloured
box shows this colour and you can apply it to your picture simple by clicking
on it. If VIEWMOL is running in colour map mode, this box always shows
the same colour as the OK button (since there is only one colour map
entry assigned), but you always get your defined colour back by clicking in
this box. If you did not define a colour in the viewmolrc file, this
box is not available and if VIEWMOL runs in colour map mode no colour
editing is possible (since no colour map entry was assigned).
If none of the colours in the boxes satisfies your needs you can set up your own
colour by clicking with the left mouse button in one of the red, green or blue
bars. The bar will be set to the position of the mouse pointer and the colour
changes correspondingly. If you use the middle mouse button all three colour
bars are set to the same position, i. e. you get a gray shade. The OK
button and the colour in the picture you want to change show the currently selected
colour and by clicking onto the OK button you change your colour permanently.
If you run VIEWMOL in colour map mode and have not defined a colour in
your viewmolrc file, the three colour bars do not appear, since they
cannot be used in this case.
