Not as a straight swap; see the closer alternatives below. Poor match (ΔE 35). Forged Red is noticeably darker, much more saturated, cooler than Sycorax Bronze.
The same difference applies the other way round: Sycorax Bronze is noticeably lighter, much more muted, warmer.
ΔE is the colour difference between our two swatch estimates: under 2 is a perfect match (you’d struggle to tell them apart), under 6 very close, under 10 close, under 15 fair, under 20 loose, under 30 very loose, and 30 or more a poor match. Real paints also differ in finish, coverage and how they thin, so test before you commit.
