PixelMaterialPixelColors Property

Gets or sets a Color4 array that specifies the colors for each pixel. When color's alpha is 0, the pixel is not rendered. When PixelColors array is set, the PixelColor is used as a mask that is multiplied with each color defined in the array (set PixelColor to White to use the values specified in this array). When null, the color of all the pixels is set by the color defined by the PixelColor property. When individual values of PixelColors are changed, you need to call UpdatePixelColors method for the changes to take effect.
