Relaxed Khaki in Behr

The closest Behr paint to Sherwin-Williams Relaxed Khaki (SW 6149) is Windsor Tan MQ2-26, a delta-E of 1.36 away — close enough to swap without anyone noticing, though a large sample in daylight will show the difference.

Light reflectance is effectively identical, 50.5 against 51.0. Undertone reads as yellow against yellow undertone, at chroma 15.1 and 13.8.

Codes are not transferable between manufacturers and no brand publishes a conversion table, so every figure here is measured from the published hex values rather than taken from a chart.
