DMC 840 to Cosmo: Thread Conversion

Cosmo 2531 is a close match for DMC 840 Medium Beige Brown. At the mid-value position, brand differences in undertone and finish are most visible — the eye reads color differences most accurately in mid-tones rather than at dark or pale extremes. Cosmo's softer hand and slightly different surface quality may make their version of this brown read marginally differently in finished work. Testing alongside your other beige brown family colors before substituting 840 specifically is important, since this color anchors the family's visual identity.
