As a text color on white, Khaki has a contrast ratio of 2.11:1, which fails WCAG AA even for large text. On black it reaches 9.94:1 and passes AA for normal text. If you use Khaki as a background, put black (or very dark) text on it. The APCA lightness contrast is Lc 63 for black text and Lc -46 for white text.
Its perceptual complement is #A1B4D2, close to silver. Colors that look most similar are sand, tan, dusty rose. It looks fairly similar to people with red-green color blindness (ΔE 1), so its meaning mostly survives.
