Since it's blue I assume you have the backdrop turned on. If so all you have to do is COLOR BACKDROP 0.

Cls only clears 2d like text, lines, etc.

The "3d-screen" is the backdrop and you have to recolor it using the COLOR BACKDROP command. (For black it would be Color Backdrop 0)

I think the following should help.

backdrop on
Color backdrop 0
sync

Also if you want to have a texture in the background, rather than just black space then you could do... (note "imagename" needs to be a texture you have created in PSP or Photoshop say but you can export your images as bmp, psd or a number of other extns that DB recognises (i.e. DB isnt just limited to png files).


load image "imagename.png",1
make object plain 100,100,2
Texture object 2,1
Position object 2,0,0,0
Position camera 0,0,0
point camera 0,0,0
do
sync
loop

If you want a texture for the backdrop and it's seamless you can also you the TEXTURE BACKDROP command. Although the downside is that it maps the texture onto the backdrop as 2 rows of three tiles.
