Something along the lines of:
colour=GetPixel(x,y)

I find it peculiar that AppGameKit lacks this functionality, unless I have missed it? (I have searched for quite a bit.)

in agk its possible to use GetImage( imageID, x, y, width, height ) or see SetRenderToImage ( colorImage, depthImage )
and then CreateMemblockFromImage
there you can get the rgb values, not the best way but it works.
from the backbuffer the alpha value is missing.

ok, but i see you not free the memblock. DeleteMemblock ( memID )
maybe also better use a fix image id. GetImage( imageID, x, y, width, height ) and maybe a static memblock too CreateMemblockFromImage( memID, imageID )
its also possible to make a color integer from it with MakeColor , read later with GetColorBlue ( color ) GetColorGreen ( color ) GetColorRed ( color )

if you use this systax you can generate this hex value in one row
rgb$=Right("0"+Hex(a),2) + Right("0"+Hex(b),2) + Right("0"+Hex(c),2)
