The game is tile based so each tile is 64x64 pixels, I am using my own code to create vertices then put them into an SMesh and then texture it. The whole terrain is 960 by 960 tiles however it is broken down and loaded into chunks of 96 x96 tiles. As a result of this my texture for the whole terrain is 961 by 961 pixels, and I want each tile to be one solid color, almost like the one shown in the picture below:

In this example, you can clearly see the tiles and they each have a slightly different colour.
here is the exmaple of my game:

The colour is placed at each point (vertex), and the tile becomes a merged result of the 4 colours. Is there any way I can make the tile 1 solid color with no blending.
Any advice is appreciated. Thankyou
