The colors of different parts are sometimes linked. For example, changing the hair color sets the eyebrows to the same color; on males, the beard is also set to the same color. I have noticed this behavior on the following boffs: human male, human female, alien male, Klingon female. Note that this bug may be related to the boffs themselves rather than just the tailor. The bug doesn't affect the captain or the boffs you acquire from the tutorial and "Stranded in Space". This bug is currently live on Holodeck as well as on Tribble.
