Olive drab pants are a muted green color, so they pair well with a variety of colors. For a classic and versatile look, a white or cream shirt would complement the earthy tones of the pants. For a more bold and modern approach, a navy blue or burgundy shirt could also work well with olive drab pants. Ultimately, the choice of shirt color will depend on the occasion and personal style preferences.
