I think this a quite easy question for an expert, but I do not manage it:
In a database I have a field where items are in that are awaited for a certain date. If the items are not back by that date the row is paint in red. Now I want that the color is not only red but a certain tone of red depending on the days the item is not in time for ex. the item is in delay for 100 days, the row is dark red, for 50 days a lighter red and so on. I tried with: brush.color:= RGB(255,0,0) and that's OK only with red. How must I insert the RGB-values to have different shades of red ?
