Hi!

From what I know, there could be 10 color pairs that define colors for different elements include the slected item. Try:
DEFINE BAR 1 OF colorlist PROMPT "Red" COLOR ,RGB(254,0,0,255,0,0),,,RGB(0,0,127,0,0,128),RGB(0,0,127,0,0,128)

5-th define back color and 6-th - fore color of the item when it is selected.

You can use spaces instead of the caption:
DEFINE BAR 1 OF colorlist PROMPT " " COLOR RGB(255,0,0,255,0,0),RGB(255,0,0,255,0,0),RGB(255,0,0,255,0,0),RGB(255,0,0,255,0,0),RGB(255,0,0,255,0,0),RGB(255,0,0,255,0,0)

Above generates line that contains only red background does not matter if you select item.

>This will create a Red bar as the 1st element. The name "Red" will only appear when you highlight that row because of the highlight color settings of the combo box. I am sure one can set the highlight colours to a dynamic setting to reflect the current highlighted element? I'll try it.
