Each variant takes the original 4096x512 hazard textures (one sheet for left, one sheet for right, one set each for standard and refined concrete) and recolors them. Each sheet (Roughly 16 in total) is ~3.5MB each. If you have a way to apply them as simple pattern overlays that don't include the concrete texture I'd love to hear it. If you don't please yell at Wube and not me thanks?
