The emission spectrum of the element lithium is shown below.

A line spectra with one purple line left, 4 blue lines, two green lines, one orange line and one red line.

What is the best estimate of the color that will be seen when a sample of lithium gas absorbs a lot of energy?

mix of blue and green

Mix of blue and green.

Reason: the emission spectrum shows many strong blue and green lines (fewer red/orange lines). When lithium gas is excited it emits (and absorbs) at those same wavelengths, so the overall visible color will be dominated by the blue/green lines.
