pallor (n.) Look up pallor at
c. 1400, from Old French palor "paleness, whiteness" (12c.) and directly from Latin pallor, from pallere "be pale, turn pale," related to pallus "dark-colored, dusky," from PIE root *pel- (2) "pale; gray" (source also of Sanskrit palitah "gray," panduh "whitish, pale;" Greek pelios "livid, dark," polios "gray;" Old English fealo "dull-colored, yellow, brown;" Welsh llwyd "gray").
[P]aleness in the Mediterranean is not so much the lack of color as a sickly, yellowish, sallow complexion, compered here to the hue of a gilded bronze statue. Sappho compared it to the color of dead grass. [Daniel H. Garrison, note on pallidor in poem 81 in "The Student's Catullus, 2nd ed., 1995]
