Yes, blue is the color they are moving to, hers should be blue too, it just sounds like hers is not automatically updating to the latest software (our d10-200 didn't autoupdate either when it had the green menus), so if she wants the blue menus, she has to do a manual update.
Doing a manual update:
Open the front door where your card goes, there is a red button, get your remote in your hand, and press the red button, then when the tv screen says "Hello, your directv reciever is starting up", press 02468 on your remote (do not hit enter).
You may have to try it a few times to get it, when you get it it will say "Almost there" then, something like "A software update was found, downloading"
If there is no download ready, it won't say anything special.
Keep in mind, not all areas of the country gets the updates at the same time, so forcing does not mean you can get it if it's not ready for your area.
