No the recipe with the chips that yields 4 is going to be replaced by the alumen recipe that yields one. It's under the "Updated Recipes" instead of "new recipes" so the old way to make leather is being entirely overwritten.
@Fleur you seemed to understand it =P All your assumptions are correct. I'm guessing we are just getting basic dye colors now and others will likely return eventually. The other case could be that different materials make different shades of colors, but I don't think it is likely.
