I dont know if you can make it coloured like that but i know you can have fading coloured names. On a forum the admin had my name fading from a dark blue to a red. It has something to do with colour or hex codes and all. Red is ff0000 and dark blue is 0000ff for example.
Im not sure how to do it though. If you know any staff members who have their names coloured, i would ask them about it. Im not really sure at all :\
