Have you tried the Point Command?

Color = Point(X,Y)

You have to use this command on the screen or on a Bitmap.

+ Code Snippet

Load Bitmap 1,"C:\Image.Bmp"
Set Current Bitmap 1
Color = Point(10,10)
Set Current Bitmap 0
Print Color
Wait Key

If you want to search the whole image then you can do this like so...

+ Code Snippet

       Load Bitmap 1,"C:\Image.Bmp"
Set Current Bitmap 1
               For x = 1 To Bitmap Width(1)
               For y = 1 To Bitmap Height(1)
                   Color = Point(x,y)
              Next x
              Next y
Set Current Bitmap 0
     Delete Bitmap 1
             Print Color
          Wait Key

here, try this

+ Code Snippet

dim color(1000,1000)
load bitmap "mypic.bmp"
rem lets pretend this image is 32X32 pixels so as not to interfere
rem with our 1000x1000 px array
for y=0 to 31
 for x=0 to 31
  rem find the color @ the x,y co-ordinates and place them in an x,y
  rem array variable
  color(x,y)=point(x,y)
 next x
next y

end

hope that helps
