The record selector, like command buttons and page tabs, is one of those things whose color is set by the Windows color scheme on any given PC. On the buttons or tabs you can change the color by superimposing a label of your desired color over the control and making the control itself transparent. But to do that the item has to appear in Design View. Unfortunately, the record selector doesn't! The only possible solution I can think of would be to go to the form's Properties section and mark "NO" so that the selector wouldn't be displayed, and then add your own controls (command buttons) shaped to mimic the record selector.
Hope this helps!
The problem with making anything foolproof...is that fools are so darn ingenious!
