Chemical reactions Quote by Sam Kean
““The color of the emitted light depends on the relative heights of the starting and ending energy levels. A crash between closely spaced levels (such as two and one) releases a pulse of low-energy reddish light, while a crash between more widely spaced levels (say, five and two) releases high-energy purple light.””

Light color emitted in atomic transitions depends on energy level gaps; larger gaps produce higher-energy (purple) light, smaller gaps produce lower-energy (red) light
In simple terms: Energy differences dictate emitted light color
