changing colors of vertices

I have only just started looking at Bmax now that its released for PC, and here is my first question:

Framework BRL.BlitzGL
Import BRL.System
Import PUB.OpenGL
Import BRL.linkedlist
Strict

Const SCRX=1024,SCRY=768
Type color
 Field r#,g#,b#,a#
End Type

Type vec3
 Field x#,y#,z#
End Type

Local ambient:color = New color
ambient.r = 0.2
ambient.g = 0.5
ambient.b = 0.7
Local position:vec3 = New vec3
position.x = 5.0
position.y = 13.0
position.z = 15.0

Type points
	Field x#, y#
	Field R, G, B
End Type

Global list:TList=CreateList()
Local mo:points = New points
mo.x# = -1
mo.y# = -1
mo.r = 255
mo.g = 0
mo.b = 0
ListAddLast list,mo
mo:points = New points
mo.x# = 1
mo.y# = -1
mo.r = 0
mo.g = 255
mo.b = 0
ListAddLast list,mo
mo:points = New points
mo.x# = 1
mo.y# = 1
mo.r = 0
mo.g = 0
mo.b = 255
ListAddLast list,mo
mo:points = New points
mo.x# = -1
mo.y# = 1
mo.r = 255
mo.g = 255
mo.b = 255
ListAddLast list,mo

Global angle:Float = 0.5

' init OGL
bglCreateContext(SCRX, SCRY, 32, 0,BGL_BACKBUFFER|BGL_DEPTHBUFFER)
glViewport(0,0,SCRX,SCRY)
glMatrixMode(GL_PROJECTION)
glLoadIdentity()
gluPerspective(45.0,Float(SCRX)/Float(SCRY),1.0,100.0)

' create light and position it
glLightfv GL_LIGHT0, GL_AMBIENT, Varptr(ambient.r)
glLightfv GL_LIGHT0, GL_POSITION, Varptr(position.x)
glEnable(GL_LIGHTING);
glEnable(GL_LIGHT0);
' set render options
glShadeModel(GL_SMOOTH)
glEnable(GL_DEPTH_TEST)
glEnable(GL_CULL_FACE)
glMatrixMode(GL_MODELVIEW)
' move camera
glTranslatef(0.0,0.0,-20.0)

bglSetSwapInterval( 60 )

While Not KeyHit(KEY_ESCAPE)
 glRotatef(angle,0,0,1)
 glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT)

glBegin(GL_QUADS)
For mo:points = EachIn list
	glColor3i( mo.r, mo.g, mo.b )
	glVertex3f( mo.x#, mo.y#, 0 )
Next
glEnd()

bglSwapBuffers()

Wend
End

In the above code, why doesn't the quad have the colors that I set?

Try glColor3b, it deosn't need to be an integer

Don't know why it doesn't work with Color3b or Color3i, but it will work if you use Color3f(the color values must be a number between 0.0 - 1.0)
Since you have light enabled you also need to call...
glEnable(GL_COLOR_MATERIAL)

Yes it seem to work with Color3f , and I didn't know about the GL_COLOR_MATERIAL, so thats good to find out. I guess its back to my OpenGL Super Bible and read a few more chapters, :) Thanks for the help so far guys.
