Red Pigment can be obtained when processing Red Flowers in a Processor. 1 block of Red Flower will give 4 Red Pigments. Red Flowers can be found growing on birch-like Ashenwood-trees in Grassland, Woodlands, Forests and valleys between Mountains, and they will grow slowly in time on Ashenwood Leaves, even in artificial biomes. As Pigment is merely a crafting-material, you cannot place Red Pigment not can you consume it; you cannot even put it into the quick-bar.
