A method for manufacturing a composite blank is disclosed. The method for manufacturing a composite blank comprises the steps of: (a) filling a mold with each of a composition for a first composite blank, having a first color, and a composition for a second composite blank, having a second color, so as to manufacture a laminate comprising a composition layer for a first composite blank/a composition layer for a second composite blank; (b) applying pressure to the laminate filled in the mold so as to cause a part or all of the composition for a second composite blank, of the composition layer for a second composite blank, to penetrate the composition layer for a first composite blank, thereby manufacturing a laminate having a color gradient; and (c) curing the laminate having a color gradient so as to manufacture a composite blank having a color gradient, wherein the composite blank manufactured by the method for manufacturing a composite blank has a color gradient.
