If we want to take even more users, we should try to compare Mageia to old Gael Duval times Mandrake. How?
Old Mandrake had it's own palette with Orange(Yellow), Blue and White colors on it. As I think, it's would be good to reuse it for greater good.
Second that i have to say, default artwork looks like it was created in 2006 or so. It's not that bad, but ugly. Look at Mint for example - transparency, full color gradients, original colors and most important - wallpaper. Do you remember how to default Mageia 2 wallpaper looks like? Strange thing, I don't remember it too. But still after 10 years on Linux I still remember how to WinXP wallpaper looks like.
Third. It's really important where is from distro goes in terms of country, culture etc. Of course Linux are international project, but Mandrake creators was French, and it's awesome since most of people have great associations with France/Paris/Magic. It must be used in distro artwork/PR.
