We demonstrate that a simple spectral sensor can measure the changes in brightness and color that take place during an annular solar eclipse. This color change is due to the Moon blocking the bluer light shining directly from the Sun's central face while allowing an annulus of limb-darkened light to reach us. This initial experiment was plagued by clouds, and we look forward to repeating this experiment during future eclipses.
