This also applies to the color codes: all color codes that you can get through the Adsense interface are legal.
Other combinations are not.
This becasue Adsense automatically adjusts some colors depending on other colors, to avoid tricks like hiding the "Ads by goooooogle" text.
When generating your ad code, I recommend choosing a border and background color for your ads that matches the background color of your website. This will allow you to do what you have described.
For example, if your background is white then you will want to choose a white border and white background for your ads.
