Troye Sivan [1] has proven he looks great in a lot of hair colors, but our heart skipped a beat when we saw the glimpse of a silvery hue. The Australian singer posted an image of the back of his head on Instagram that revealed his hair was a silver shade [2] that shimmered in the sun. The next day, however, Sivan posted another image of himself that was back to his brown shade [3].

It's possible the star used a temporary hair paint like L'Oreal Paris Colorista 1-Day Hair Color Spray [4] ($7) to get the shimmering look, but we think it looked so good that he should consider wearing it in a long-term capacity.

Check out Sivan's current and past hair colors, ahead.
