No shortage of substitutes here, Deep Blue from AK Interactive matches at 95 percent and 7 brands carry a strong same-finish near-match. Sea Blue is a dark moderate blue with a cool undertone. It builds a smooth gradient with Dark Blue underneath and Royal Blue on the highlights, all in the Tamiya line. Bottom line: run out mid-project and another brand will get you within a shade.
