It is slightly confusing. If you are using an Indexed image, then use
the Pixels[] property. If you are not using an Indexed image, then use
the Colors[] property.

Attached is an example program that generates a Minecraft like grass
block (texture) and then outputs it to a PNG file. I hope the example helps.

Regards,
