BGE color

hello when i use a command:

object.color=1,0,0,1

in blender my object’s color will not be red unless i run the game in with Shading on"Singletexture".

in GLSL shading there is no color. how do I make GLSL shading show color changes on runtime. Thankyou.

In the Material Options there is a Checkbox “Object Color”. Check it and the Script should work.
