That would depend on the gas most prominent in that area of the sky and the quantity of gamma radiation. I couldn't say for sure, but the sky would probably glow a bit at night if it was a high quantity of gamma radiation, maybe mainly a slightly blueish hue at night and not much different during the day since nitrogen is 78% of the atmosphere's composition and nitrogen emits blueish light when it contacts radiation.
Want to test it? :P

While the gamma rays would be invisible, if they hit a molecule or an atom, they would emit light as a tiny flash (depending on how many there were). Researches use this effect for ground based researching of gamma rays -

Amateurs who do imaging with CCD cameras, have also captured gamma rays and other hight energy particles that have struck their imaging systems. Most go unnoticed and are removed as a product of image processing. But here's what they look like -

Normal, considering we (the Earth not humans) are being hit by them constantly (research cosmic rays)
-
We are constantly being hit by gama rays so the color isn't visible.

Gamma rays are invisible.

It wouldn't make things look any different and in fact that happens all the time anyway.
