Both of these are single-method interfaces. <code>IBlockColor</code> takes an <code>IBlockState</code>, an (<code>nullable</code>) <code>IBlockDisplayReader</code>, and a (<code>nullable</code>) <code>BlockPos</code>. <code>IItemColor</code> takes an <code>ItemStack</code>. Both of them take a parameter <code>tintIndex</code>, which is the tint index of the face being colored. Both of them return an <code>int</code>, a color multiplier. This int is treated as four unsigned bytes, alpha, red, green, and blue, in that order, from most significant byte to least. For each pixel in the tinted face, the value of each color channel is <code><nowiki>(int)((float)base * multiplier / 255)</nowiki></code>, where <code>base</code> is the original value for the channel, and <code>multiplier</code> is the associated byte from the color multiplier. Note that blocks do not use the alpha channel. For example, the grass texture, untinted, looks white and gray. The <code>IBlockColor</code> and <code>IItemColor</code> for grass return color multipliers with low red and blue components, but high alpha and green components, (at least in warm biomes) so when the multiplication is performed, the green is brought out and the red/blue diminished.

If an item inherits from the <code><nowiki>builtin/generated</nowiki></code> model, each layer (“layer0”, “layer1”, etc.) has a tint index corresponding to its layer index.

If an item inherits from the <code><nowiki>builtin/generated</nowiki></code> model, each layer (“layer0”, “layer1”, etc.) has a tint index corresponding to its layer index. For blocks, the “particle” layer is index 0.
