it already supports Vertex Colours... you'll have to import a DirectX 8.1/9.0 X model to be able to use them straight off the bat though, and it MUST be exported with an official exporter from Microsoft/Alias|wavefront/Avid themselves - else you can forget about the FVF feature support.
John's Exporter for Milkshape might support exporting them but Milkshape itself doesn't so i'm not sure (you'll have to wait for Milkshape2 as that will)
don't worry though because right now there is a simple editor being developed so that you can alter the states of your models, then import them later by using the
'make memblock from file', 'make mesh from memblock' & 'make object' commands.
and DBO full support is promised for patch5 so you can export models directly to DBO format (which I'm still waiting on that format setup Mike!!)
the defualt DB code is setup to accept Vertex Colours standardly, which will be grey i there is no current colour ... but you can alter that by putting it into a memblock and editing the 4position
like
function WriteVertexColour( colour as dword, vert as dword )
local ofs as integer
local pos as dword
ofs=12
pos=vert*36+12+ofs :`// 36 byte range, 12 ofset from vertex 0
write memblock dword 1,pos,colour
endfunction

then just convert back
