Draw with one color , but display four color

Hi there,

I’m a newbie working on a project using Opengl ES 2.0 ,
I draw a polygon with one color, but when I take a screen shot, and zoom in, I find four color.


How can fix this? or where the problem may lie?
surface ? dithering ?

I fixed it.
It is dithering. I disable it, then it works OK now
